Key Price Drivers for This Card
Before deciding whether the current price is strong or expensive, compare the characteristics that can materially change what collectors are willing to pay. The current listing is asking USD 600.00, so these factors are the best starting point for checking that ask against other copies.
- The 2026 release and how much collector demand exists for that year.
- Demand for the 2026 Topps Signature Class set compared with other issues of the same player.
- Whether comparable sales match card number R 16.
- The raw condition shown in the photos, including centering, corners, edges and surface.
- Whether collectors consistently recognize this exact release as a rookie card.
- The listed card features, especially RC.
How to Judge the Copy in the Photos
For a raw copy, zoom in on the front and back photos before buying. Check centering, all four corners, edge wear, surface scratches, print lines, dents and any marks that may be hard to see in a single photo. Ask for additional images when an important area is hidden by glare or a sleeve.
For a modern card, inspect glossy surfaces carefully because scratches, dimples, print lines and small edge defects can be easier to miss in listing photos. Chrome style and foil finishes can show flaws differently depending on lighting. eBay currently labels the listing condition as Ungraded, but the photos and grading information should carry more weight than the marketplace condition field alone.
Price History and Market Trend
The current eBay asking price is $600.00. There is not enough exact match history in the available data yet to calculate a useful six month trend.
Collector Checklist
There are a couple details that stand out in the listing. Sport is listed as Basketball, team is listed as Dallas Mavericks and features include RC. For an ungraded card, spend some time with the photos. Centering, edge wear, corners and surface marks can make a big difference in value. The rookie designation is worth checking against the exact release. The year, set and card number are the best details to confirm before buying.
What Could Hold Back the Grade
Common reasons a card from this type of issue can grade lower include surface scratches, print lines, dents or stains, factory print defects that affect overall eye appeal and centering on the front and back.
For numeric context, PSA publishes an approximate PSA 10 centering tolerance of 55/45 on the front and 75/25 on the reverse. PSA describes a Mint 9 as centered no worse than 60/40, so a small centering shift can be enough to separate a 9 from a 10 even before surface, corner and edge flaws are considered.
PSA grading standards. Population figures change as additional cards are graded.
Building a Useful Comp Set
When researching a Cooper Flagg card, start narrow and widen the search only when exact matches are scarce. For this listing, try to match year 2026, set 2026 Topps Signature Class, card number R 16 and similar raw condition.
Use sold prices before active asking prices when both are available. An active listing tells you what a seller wants, while a completed sale gives a better signal of what a buyer actually paid. Compare the current USD 600.00 ask with that matched group rather than with a broad search for every Cooper Flagg card.
