Sometimes.
I forget who, but there was one guy in 74 that I had maybe 20 of. The others I had maybe a few where I'd gotten three.
And 94 Signature rookies I kept getting this same guy from the Yankees

Of course, later I was happy to have three signed Jeter cards. (Down to the one keeper now)
In one early batch of 81 Donruss each pack had 11 of the same card and 4 random ones. Not messed with as I saw the case get opened. The dealer pulled them and sent them back before I could get any, one kid got 11 Yaz cards, his friend got 11 checklists.
