? about Topps variation cards of players
I have taken a leap to complete a Master Topps Set of a certain player. I am astounded at the crazy amount of variation cards contained in the set. It goes from refractor, xfractor, chrome, pink, blue, purple, orange, black, gold, copper refractor, chrome gold, chrome black refractor...it goes on and on and on.
My question is, where were these variation cards found? Were there special sets, or special inserts into yearly Topps sets?
Some of the Allen & Ginter cards had regular backs, Ginter backs, Bazooka backs and ad backs, not to mention minis and black borderd cards...the front is the same pic. Obviously a money maker for Topps during that time, but was just curious how they sold these variations, obviously they weren't single card sales.
I would think some of these cards are indeed rare...as it sits, I'm right at 30 cards short, and it'll probably be a long time before and if I complete the set, but fun so far.
