Baseball Card Tools

Which tool do you need?

The three tools answer three different questions, and they chain together in one order:

• "What have I actually got?" — start with the collection value tracker. Log each card with a value pulled from real eBay sold prices and you get a running total, plus a list you can act on instead of a shoebox you're guessing about.
• "Could this card grade a 10?" — measure it in the centering tool. Centering is the one grading factor you can measure objectively at home, and it sets a hard ceiling on the grade before corners, edges and surface are even considered.
• "Is grading it worth the money?" — run the grading ROI calculator. It weighs the PSA 10 upside against the real chance of a 9, subtracts the fee and round-trip shipping, and tells you the odds of a 10 you'd need just to break even.

All three run entirely in your browser. Nothing is stored on our servers, there's no signup, and every value you type stays on your device. Where a tool needs a real market price, it links you straight to eBay's completed-sales results for that exact card — sold prices, not asking prices, are the only honest input.
