I've been buying some new cards and selling some of my childhood collection on ebay lately, and it's been really challenging to know what fair market value is for cards. Beckett says one thing, but that doesn't match with what happens on ebay.

I'm a software developer, and I'm working on tackling this problem with an online tool that allows you to see sales volume, price trends, and real time pricing information for sports cards. It's coming together really well!

If anyone is interested in early access to this tool, check it out here:

Would love some input and feedback from other card collectors!
