I've not touched upon the somewhat puzzling 1971 Topps Greatest Moments set in quite some time and my prior peeks have been somewhat cursory. I ran through the two proof sheets and before that gave a super short capsule review in a kind of catchall post a while back so it's high time I readdress these oversized (2 1/2" x 4 3/4") cards.
Their origins in the hobby are a little murky but the set of 55 was seemingly tested in Brooklyn and the Boston metro area during the summer of 1971. It's likely one or two other areas saw them as well (you would have to surmise test stores around the Topps plant in Duryea, PA had them) but Brooklyn and Boston are the only areas I've seen positively identified. A display box is known as is a test wrapper:
While the box clearly says they came with gum, examples of the cards showing this are hard to find, at least in my experience. The wrapper is typical of the era's test issues; this one is courtesy of Friend o'the Archive Al Richter and it is ridiculously hard to find:
The earliest hobby reference I can find is in October 1971, where The Trader Speaks editor Dan Dischley gave his readers a checklist and quick rundown:
The cards look super nice. I have three, two of which are Mets and those two are also short-printed. Topps must have really liked the black border look in '71 - I know I do:
As you have no doubt observed having read this far, the cards are mostly grouped by team.
Bob Solon, writing in the same October 1971 issue of TTS, was unimpressed by Topps "distribution" network shenanigans, although his prediction from 1972 was wrong:
Looks like they lost a bunch of SP's and DP's alike based upon the Mint ones left unscathed by the blaze! Despite this setback, it seems most extant examples came from Card Collectors Company.
PSA has graded just under 4,900 of these, or about 63 of each slot (of 77) on the press sheet. Clearly an aftermarket supply, deservedly derided by Bob Solon, was made available and three or four favored dealers got some post-test stock one way or the other. The SP/DP pops run roughly 50-60/110-120 and of course for every graded card, especially black bordered ones, there are resubs and superstar skews, plus raw examples still in the wild (at some kind of multiplier like 3x I'd say if you sleuth eBay listings) but it's a good confirmation of the double print vs. single print ratio.
The set is one of the better looking extras issued by Topps over the years IMO.
