Enjoyed reading all the posts...appreciate that...
I believe in Base and Master like others for sure...and do have several variation cards through the years, especially some of the 67 Topps variations...but in the case of the Dalrymple and Clendenon in the 69's, they literally have different words and pictures...I have to have those. If there is an extra dot, missing or added ink, a green part of the bat...I'm interested and want them, but not a priority.
Man, not saying a 52 Topps set isn't complete without the Mantle A and B is rough!

If I had both, I would agree with you, if I only had one, I probably wouldn't...haha. I think I'll work on just getting one first...
