Just turned 30 yrs old last month and I have several vintage autos(probably a couple hundred team signed baseballs) and bball cards, but my main focus is game used bats and jerseys. I have about 750 game used bats with about 85% of those being pre 1980. I have over 200 game worn jerseys but most of those aren't vintage. Most of them range in the 80's and 90's.
I'll have to check my HOF number on those.
