⑤Where Should You Buy PSA- and ARS-Graded Cards? Shops vs. Flea-Market Sites
PSA- and ARS-graded cards can be purchased not only from trading-card shops and online stores, but also on flea-market platforms such as Mercari.
Even for the same card and the same grade, the place you buy from can change factors such as price, how easy the item is to find, how easy it is to inspect the actual item, and how much you need to verify yourself before purchasing.
Especially with expensive graded cards, it is wiser not to divide options simply into “shops are safe” and “flea markets are risky,” but to understand the characteristics of each and choose where to buy accordingly.
This article focuses specifically on buying PSA- and ARS-graded cards and compares card shops with flea-market platforms.
Advantages and disadvantages of buying from a shop
Here we will look at characteristics that apply when buying graded cards from a shop, whether it is an online store or a physical store.
- The seller is clearly identified as a store or business, making contact details and sales terms easier to check
- Information such as the card name, grading company, grade, and price is often organized, making the item you want easier to find
- Specialist trading-card shops manage product information with cards and graded items in mind, so comparing product details may be easier than in person-to-person transactions
- If an issue such as receiving the wrong item occurs after purchase, you can first contact the store according to its guidance and policies
- Because stores have purchasing and operating costs, the same card in the same grade may be priced higher than on a flea-market platform
- A shop can only sell inventory it has secured, so the card or grade you want may not always be available
- Terms for returns, exchanges, cancellations, and similar matters vary by shop, so for expensive items you should check the sales conditions before buying
Now that we have covered the general characteristics of buying from a shop, let us separate online stores from physical stores and see what differs.
Online stores vs. physical stores
Even among trading-card shops, what you can check before buying differs between online and physical stores.
One major advantage is that you can search products from shops throughout the country. Even PSA- or ARS-graded Old Relief cards that are unavailable at nearby stores may be found online.
On the other hand, you generally have to judge the item from the posted photos and description.
When viewing an expensive graded card online, it is worth checking the following points.
- Are the posted images photos of the actual item being sold?
- Can you see both the front and back of the card?
- Can you clearly see the grading label?
- Can you tell the condition of the holder?
The biggest advantage of a physical store is that you can inspect the actual item. In addition to the card’s appearance, scratches and scuffs on the holder may be easier to see in person than in photos.
Even among high-grade items such as PSA 10 or ARS 10, you may feel there are individual differences in how they look as collectibles.
It is also better to evaluate the card’s grade and the holder’s current condition separately. The grade reflects the card’s condition at the time of grading, while the holder itself can acquire scuffs or scratches during storage and distribution, so check the holder’s condition separately when buying.
For cards costing tens of thousands, hundreds of thousands of yen, or more, being able to inspect the actual item and buy only after you are satisfied can be a major advantage.
The disadvantage is that you have to visit the store, and there is no guarantee that the card you want will be in stock there.
Advantages and disadvantages of buying on flea-market platforms
- There are many listings, including cards and unusual grades that may be difficult to find in shops
- You may find graded cards released from individual collectors’ collections
- Because sellers set their own prices, some items may be cheaper than at shops
- Depending on the seller, price negotiation may be possible through comments or messages
- Even for Old Relief cards with limited circulation, you may be able to compare multiple listings
- The detail and quality of product descriptions and photos vary greatly by seller
- Sellers also vary in how knowledgeable they are about graded cards
- Some listings provide little information, such as only one front-facing photo
- Because sellers are free to set prices, a flea-market listing is not automatically cheaper than a shop
If you buy without checking past transaction prices or current listings for the same card, you may end up paying substantially more than the market level.
Compare the “total amount paid,” not just the item price
When comparing places to buy, it is useful to look not only at the displayed item price but also at how much you will ultimately pay in total.
When calculating the total payment, also check the following costs.
- Item price
- Shipping
- Fees charged to the buyer
- Authentication fees if you use an authentication service
Even when the displayed price is slightly lower, shipping and fees may make the final payment higher than for another item. When comparing options, looking at “how much will I ultimately pay?” rather than only “how much is the item?” can help you shop more economically.
Points to watch when buying on a flea-market platform
When buying PSA- or ARS-graded cards on a flea-market platform, it is important to inspect the listing photos carefully rather than looking only at the grade and price.
Authentication services provided by flea-market and marketplace platforms
Some services route an item through an authentication center before it reaches the buyer and check its authenticity. Here we compare three points relevant to buying graded cards: how the service works, which items are eligible, and the fee.
- How it works: After a sale is completed, the seller sends the item to SNKRDUNK, where professional authenticators perform authentication and inspection. Only items that meet the standards are shipped to the buyer.
- Eligible items: PSA-, BGS-, and ARS-graded items are also handled, and authentication and inspection are performed while the card remains in its holder.
- Fee: The buyer’s authentication fee is ¥0.
- How it works: Eligible items are sent by the seller to Mercari’s authentication center, and products that meet the authentication standards are then shipped to the buyer.
- Eligible items: The service can be used for eligible categories and brands when the seller has enabled Anshin Authentication. Graded slabs from official grading companies designated by Mercari, including PSA, ARS, and BGS, are also included among eligible items.
- Fee: As of August 2026, the fee for trading cards is ¥1,700 (tax included) per card. The authentication fee is free when the purchase screen shows free authentication, such as for items priced at ¥150,000 or more.
- How it works: For listings marked “With Authentication,” the buyer can choose whether to use authentication during the purchase procedure after winning the auction. Items using the service are sent to the authentication company, where authenticity and item condition are checked, and items that meet the standards are shipped to the buyer.
- Eligible items: Yu-Gi-Oh! is also an eligible brand, and PSA-, BGS-, and ARS-graded cases are supported. There are specified conditions regarding eligible categories, brands, listing details, and other factors, but the starting-price requirement was removed on April 13, 2026.
- Fee: As of August 2026, the authentication fee for trading cards is ¥1,600 (tax included), paid by the winning bidder.
Note: Yahoo! Flea Market
For Yahoo! Flea Market, as of August 2026 the official guidance does not confirm a system that sends purchased trading cards to an authentication center through a Yahoo! Flea Market authentication service. Yahoo!’s trading-card authentication is described as the “With Authentication” service on Yahoo! Auctions.
*Eligibility, fees, and other conditions may change, so check the latest information displayed by each service when purchasing.
First, use the grading label and listing photos to check the following information.
- That the item is graded by PSA or ARS
- Card name
- Card number
- Grade
- Certification number
If the grading company provides lookup information, it is also useful to check whether the information shown for the certification number matches the listed item.
With PSA, Cert Verification may display images taken at the time of grading for some items. When images are available, they can be used as an additional reference for comparing the certification record with the listing photos. However, some graded items have no images, so do not judge an item solely by whether images are available.
ARS offers a service that can issue grading certificates, but a certificate is not automatically included with every graded item. Therefore, the absence of a certificate alone does not necessarily indicate a problem. If an item is sold as “with certificate,” check the presence and condition of the certificate in the listing photos as well.
It is important not to finish authenticating the physical item in front of you simply because its certification number can be searched. In addition to the number, check the label, card, card number, grade, holder, and listing photos together. Even when using an authentication service provided by a flea-market platform, review the information available to you before purchase as well.
For expensive graded cards in particular, you may want to take another look before buying if a listing has any of the following characteristics.
- The certification number cannot be confirmed
- The text on the grading label cannot be read
- There is no photo of the entire holder
- Only the front of the card is shown
- The product description does not match the information on the label
- Only reference images are shown rather than photos of the actual item
- The price is extremely low compared with the market
- The description is extremely sparse despite the item being expensive
Of course, matching one of these points does not prove that an item is counterfeit.
However, the more expensive the graded card is, the more important it is not to buy while leaving important questions unresolved.
If there are things you cannot judge from the photos, you can ask the seller before buying or request additional photos if necessary.
When the item arrives, check the following before completing the transaction.
- Does it match the card name, card number, and grade you purchased?
- Do the grading label and certification number match the product description and the photos shown at the time of purchase?
- Does the holder have cracks or major damage?
- Are there any problems that were not disclosed in the description or photos?
- If you bought an ARS item advertised as “with certificate,” is the certificate included?
On services such as Mercari where the buyer submits a receipt rating, it is better to inspect the item first. If you find an undisclosed issue, check the seller-contact and platform guidance before submitting the receipt rating.
Key points to remember when choosing where to buy PSA- and ARS-graded cards
Different places to buy PSA- and ARS-graded cards each have their own advantages.
Shops have clearly identified sellers, and physical stores in particular offer the major advantage of being able to inspect the actual item. Flea-market platforms, meanwhile, have many listings and may offer cards that are hard to find in shops or items with attractive price conditions.
Especially for expensive graded cards, choose the seller and item after checking the following points.
- Price
- The card itself
- Grade
- Grading label and certification number
- Holder
- Seller
- Product photos
It is difficult to say that either shops or flea-market platforms are always superior. Understand the characteristics of each and choose an item you are comfortable with.
