I have two footlockers of baseball cards from the late 60s to the mid-90s. Many of those in the 80s are in complete sets sealed by Topps.
I have also several of my 1940 to 1950s cards to the Ty Cobb Museum in Royston, GA.
these days it is all about high grade slabbed cards. 9-10.
Of course you pay a percent to the grading agency which is contrary to legit appraisals.
