I created a list of 25 valuable Mark McGwire baseball cards that you should keep an eye out for when investing in baseball cards. If you see these cards ungraded at a garage sale, flea market, antique shop or any other storefront, you should pick them up! If they're PSA candidates go ahead and add them to your PSA submission pile.

Let me know what you guys think! Which cards should be on the list?
