Hi Jeff,
On the baseball side I'm really just looking for my favorite players from the 80's. 90% will probably be HOF'ers. My last 3 baseball purchases as an example were 84 Fleer Traded Clemens and Puckett in PSA 9 and a very random SGC 9.5 of the 1991 UD SP1 Jordan.
Currently working on 3 PSA Registry basic Topps player sets of:
Walter Payton: 84.62%
Joe Montana: 87.5%
Jerry Rice: 94.74% (Last card needed is at PSA now)
The basic player sets will be my focus and I am thinking about starting a Barry Sanders and LT set soon.
Full disclosure - I'm not a rich man and I buy when the funds are available which is not daily
