I have been wondering what cards define your collections. For me, Ty Cobb screams pre-war. I don't care who sees my collection, a "know-nothing" or "know it all", Cobb cards are immediately recognized and appriciated. If I had to sell my collection, everything could go, except for a few Cobbys. Don't get me wrong...I have fallen in love with adding all the commons to my sets. But the new addition of a Cobb of any kind gives me chills.
So, what are your "must have" items in your collections? Scan are always welcomed! I'm on the road again and have no access to my cards...
