The one word?
Yep, thanks to Bill at Monmouth Stamp & Coin digging through their inventory, I'm done with 1975 Topps, 1978 Topps, 1993 Topps and 2011 Topps Update. Monmouth Stamp's actually a great place to get set fills like that, where you're missing between 1-5 cards from a particular set. '75's the oldest Topps set I've finished so far, and I've now got a run of '78-'93 Topps base sets completed, too. Next stops: the '70s and the strike years! Who wants to bet that I'll finish the '70s sets sooner than the strike years?
