What's my card worth?

How to find out what your card is worth

Check recent eBay sold listings for the same card, year, set, and grade. This is the gold standard because it reflects what real buyers actually paid — not what sellers are asking. Most price guides and app valuations are based on this data, but the quality of their filtering varies wildly.

What affects a card's value?

• Player — Star players and rookies command the highest premiums
• Grade — A PSA 10 can be worth 5–20x more than a PSA 8 of the same card
• Year and set — First Bowman, Prizm Silver, Topps Chrome are consistently high-value
• Print run — Serial numbered cards (/10, /25, /99) are rarer and more valuable
• Liquidity — How many sales per month. High liquidity = easier to sell
• Momentum — Player performance, injuries, trades, and playoff runs all move prices

Does grading increase value?

Yes — graded cards typically sell for 2–20x more than raw cards. But grading costs $25–$150+ depending on the service level. The real question isn't "should I grade?" — it's "will I profit after grading costs?"

Slabfy's Grade Ladder calculates this automatically — it searches across every grade tier (PSA 7–10, BGS 9.5, SGC 10) and shows your expected profit after grading fees. No spreadsheet required.

Why are app valuations sometimes wrong?

Most card apps use algorithms that average all recent sales — including lots, reprints, misidentified cards, and non-US listings. This inflates or deflates the number depending on what junk data gets mixed in.

Slabfy filters out junk data using AI-powered smart filtering, so you see only accurate comps for the exact card you're looking at. Real data, not guesses.
