GradedGoats is a marketplace pricing and bidding platform built for graded trading card buyers and sellers. Every listing, every bid, backed by real recent sold comps — not guesswork.
Existing users — enter your credentials to access GradedGoats.
Four tools, one workflow. Built specifically for the categories where a single missed comp costs real dollars.
Search active eBay listings for graded cards across all major graders. Filter by player, set, year, grade, and price. Every result is a real, verified graded slab.
See the last 90 days of sold prices for comparable graded cards. Median, mean, range. Price your listing (or your bid) against real market activity, not guesswork.
Enter a PSA cert number, we pull the card data automatically, you set the price. One-click publish to your connected eBay account.
Watch auction lots with confidence. See suggested max bids based on recent comps. Never overpay in the last 10 seconds.
Every card in the results is AI-verified as an actual graded slab, not a title with "PSA 10" typed in the description. No wasted clicks on misleading listings.
Sign in with your eBay account in read-only mode. We can't modify your listings unless you explicitly grant additional permissions and take an action.
Whether you have 10 cards or 10,000, GradedGoats surfaces recent sold comps for each one — so you list at prices that actually sell, not too-high wishlist numbers or too-low money-left-on-table figures.
Watching an auction lot? GradedGoats shows you what comparable graded cards have actually sold for in the last 90 days — so you enter a proxy bid you're comfortable losing at, not one you'll regret winning.
We don't play favorites. Filter by grader when you want to, or compare across graders when you don't.
