⑥PSA・ARS鑑定品の相場の調べ方
When looking for PSA- or ARS-graded cards, you may see several different prices for the same card, such as ¥50,000, ¥70,000, and ¥100,000.
Of course, not every price displayed on the screen represents the market value of that card. What is especially important is to separate the current “listing price” from the “transaction price” at which a sale actually took place.
This article explains, step by step, which prices to look at when researching the market value of PSA- and ARS-graded cards, how to align comparison conditions, and how to think about cards with few transactions.
- The difference between listing prices and transaction prices

- The differences among shop retail prices, shop buyback prices, and flea-market prices
- How to think about the market value of graded cards with few transactions
Listing prices and transaction prices are different
When researching the market value of a graded card, first separate “the price at which it is listed” from “the price at which it actually sold.”
This is the price a seller or shop sets because they want to sell at that amount. The item may currently be purchasable at that price, but listings that have remained unsold for a long time are also included.
This is the price at which a sale actually took place. Examples include sold items on flea-market sites and completed auction results.
Transaction prices are the main basis for understanding the market. Listing prices are easier to use as separate information for checking “how much items are currently listed for” and “how much inventory is currently available.”
Where should you actually research prices?
When researching market prices, do not look at only one service. Check separately “prices at which items actually sold in Japan,” “current listing prices,” and, when necessary, “overseas transactions.”
You can use Mercari to check domestic flea-market transactions. Mercari has a feature for researching market prices, where you can search by keyword and distinguish between items currently for sale and sold items. Match not only the card name, but also the card number, PSA/ARS, and grade.
You can check the winning prices of previously completed listings. Use these to see prices at which auction transactions actually closed, and keep them separate from prices of currently active listings.
For PSA-graded cards, when relevant transaction data exists, PSA’s official auction price database can also be used as a reference. Because it includes results from overseas auctions such as eBay and Goldin, do not treat it as identical to the Japanese market; use it as supplementary information.
With PSA, you can verify grading information from the certification number, and for some cards, sales records and price information may also be displayed as “Sales History.” The certification number can also be used to confirm that the item you are comparing matches its grading information.
Service screens and features may change, so also check each service’s latest guidance when using it.
How should you read listing prices?
Listing prices are not “prices at which items actually sold,” but that does not mean they are useless when evaluating the market.
For example, if multiple listings appear below the most recent transaction price, the next transaction price may fall. Conversely, if only items priced above the latest transaction remain, the price at which you can currently buy may have risen.
From listing prices, therefore, check “the current asking-price range,” “the lowest price at which you can buy,” and “the number of listings.”
- Is it the same card and card number?
- Is it the same grading company, such as PSA or ARS?
- Is it the same grade?
- Are the photos of the actual item being sold?
- If shipping is charged separately, are you comparing the total including shipping?
- Does the holder have damage such as chips or dirt?
It is too early to conclude that “the market value of this card has fallen to the lowest listing” just because there is one cheapest item. Compare it with other listings and recent transaction prices.
How should you read transaction prices?
A transaction price is the price at which a buyer’s and seller’s conditions matched and a sale actually took place, so it is important evidence when evaluating the market.
However, even if there is one most recent transaction, it is risky to treat that single sale as the current market value without further context.
Reasons why a single unusually high or low transaction may occur include the following.
- A seller who wanted to sell quickly listed below the market
- Multiple interested buyers competed in an auction
- The number of interested buyers differed depending on when the item was listed
- Even at the same grade, individual conditions such as the card’s appearance or holder condition differed
- There were transaction-specific circumstances, such as the condition of the item or holder or the listing terms
Do not look only at one recent high sale and conclude that “the market rose,” or one low sale and conclude that “the market fell.” Where possible, review multiple transactions in chronological order.
Prices can differ even within the same grade
Even for the same card and same grade, such as PSA 10 or ARS 10, transactions do not always occur at the same price.
The grading grade is an important standard for judging card condition, but factors other than the grade can also affect actual transaction prices.
Examples include the following differences.
- The card’s visual appeal
- Individual differences within the same grade, such as centering or whitening
- Scratches, chips, or dirt on the holder
- Whether an ARS Certificate is included
- The certification number for PSA grading
- How clearly the listing photos show the item
- The seller’s ratings and sales history
For PSA certification numbers, some buyers look at the number with the grading period in mind. However, the card’s quality or price is not determined by the certification number alone. PSA’s official service lets you verify grading information from the certification number, which can also be used to cross-check item information during a sale.
Especially for expensive graded cards, some buyers care about “which copy to buy” even among cards with the same PSA 10 grade.
Therefore, even when transaction prices differ for the same card and grade, it does not necessarily mean the overall market has moved sharply.
When comparing transaction prices for the same grade, check not only the price but also product photos and holder condition.
If there is an unusually high or low transaction, check whether there was a reason specific to that item that could have created the price difference. This makes the market easier to assess.
How should you think about the market from multiple transactions?
After checking multiple transaction prices, do not use a single high or low sale as the market value. Instead, look at “the price range where transactions are concentrated.”
- ¥98,000
- ¥100,000
- ¥103,000
- ¥108,000
- ¥145,000
In this example, there is one transaction at ¥145,000, while the other four are concentrated between ¥98,000 and ¥108,000. Rather than deciding that “the market is in the ¥140,000 range because one sold there,” it is easier to understand the actual situation by viewing the market as centered around roughly ¥100,000 to the low ¥100,000s and checking current listing prices as well.
The “median,” found by arranging transaction prices from low to high and looking at the middle value, can also be a useful reference. In this example it is ¥103,000. Because the median is less affected by extreme highs and lows, it can help identify the center of the transactions.
However, do not treat the median itself as the “correct market price.” Consider it as part of a price range together with transaction timing, number of sales, individual differences, and current listings.
The difference between auctions and fixed-price sales
Even when looking at actual transaction prices, auctions and fixed-price sales determine prices through different processes.
If there are few bidders, the auction may end cheaply, while competition among multiple buyers can push the result above the recent market. The ending time and level of attention can also affect the result. However, if bidding is insufficient, the item may sell for less than a fixed-price listing would have achieved.
An item may be purchased at the price set by the seller, or a negotiation may result in a sale below the original listing price.
Both are useful as actual transaction prices, but “it sold for this amount at auction, so it will always sell for the same amount at a fixed price” does not follow. Separating the sales method also makes price movements easier to understand.
How should shop retail prices, buyback prices, and flea-market prices be compared?
This is the price at which a shop sells to customers. It reflects factors such as purchasing, inventory management, and store operations, so it is useful for checking “how much you would need to pay to buy from a shop now.”
This is the price at which a shop buys from customers. When a public buyback price is available, it can be a guide to “roughly how much you might receive by selling to the shop,” although the actual appraisal may vary depending on item condition and the shop’s terms.
This is the price at which an actual sale took place, such as in a person-to-person transaction. When checking “how much this card has recently been moving for,” focus on completed sales rather than prices of items still listed.
If you want to know “the price you can buy at now,” look at shop retail prices and current listings. If you want to know “the price at which items have recently sold,” look at transaction prices. If you want a guide to “what you might get by selling to a shop,” look at shop buyback prices. Use different figures depending on your purpose.
How should you evaluate cards with few transactions?
For expensive Old Relief graded cards, there may be no transaction for the same card and grade for several months.
For such cards, rather than deciding “the market is ¥X” from only the most recent sale, it is closer to reality to think in terms of a price range by combining past transactions with current listing conditions.
- If recent data is insufficient, widen the time period and review older transactions
- The older the transaction, the more you should consider the possibility that it no longer reflects the current market
- Also check the current number of listings and their prices
- If transactions are extremely scarce, treat the market as an “approximate price range” rather than a price down to the last yen
The fewer the transactions, the more a single high or low sale can change the overall impression. The scarcity of data itself can be important information when evaluating the market.
A practical flow for researching market prices
When actually researching the market value of a PSA- or ARS-graded card, checking in the following order can make the process easier to organize.
- Match the card name, card number, and rarity
- Match PSA/ARS and the grade
- Check recent transaction prices from sources such as sold Mercari listings and completed Yahoo! Auctions results
- Review multiple transactions in chronological order where possible, rather than only one sale
- Check the range where prices are concentrated and, if useful, refer to the median
- Also note the difference between auctions and fixed-price sales
- Check current listing prices and the number of listings
- Check shop retail prices and shop buyback prices separately
- When official PSA/ARS lookup tools can confirm item information, use them to cross-check comparison conditions
Following this order helps you think separately about not just “what is the cheapest price,” but also the price range in which the card has recently traded, how much it currently costs to buy, and roughly what a shop might pay if you sell to it.
What to remember when evaluating the market for PSA- and ARS-graded cards
- Treat listing prices and transaction prices separately
- Use prices from completed transactions as the main basis for the market
- Match the card, card number, rarity, grading company, and grade before comparing
- Do not judge a market rise or fall from only the most recent sale
- Look at the center and range of multiple transactions and, when useful, refer to the median
- Treat shop retail prices and shop buyback prices as different figures
- Auctions and fixed-price sales determine prices differently
- For cards with few transactions, combine past sales and current listings and think in terms of a price range
The market is neither “the cheapest item currently listed” nor “the last single sale.”
By separately checking multiple comparable transactions and current listings, you can understand the price of PSA- and ARS-graded cards in a way that more closely reflects actual market conditions.
