The cards are quite well done. Here's a few atop some unopened penny packs:
Sorry but I don't have any notes as to where that scan came from.. It could have been eBay though. I think Topps mostly sold these in the one cent packs as they had another bonus baseball set being sold in nickel packs, the so called Giants (actually named Baseball All Stars). There are nickel wrappers out there but they are not abundant.. Friend o'the Archive John Moran has sent a scan of one:
You could also buy a pack of regular baseball cards and get a coin or two as an insert-1964 was a real active year for the ancillary sets.
Here is an uncut sheet scan, I regret it does not blow up too well and you can't see which player is which. This was in the 2012 Robert Edward Auction:
The pattern can be discerned though. There are twelve rows and the double prints look like so:
Rows 1 & 9
Rows 2 & 10
Rows 3 & 11
Rows 4 & 12
Row 5 & 8 (one is upside down)
Single prints are in rows 6 and 7. The SP's are as follows (cards are unnumbered):
While I am not a huge fan of population reports in determining scarcity, the PSA totals for The Stand-Ups tell a fairly complete story. There are 12,501 total graded Stand-Ups as of April 2nd. Of this, a mere 10 are 10's and only 2.17% of the population grades out at an unqualified 9. The Giants of the same year have more cards graded (30,989) while there are 269 10's and a whopping 12,71% of the graded examples are true 9's.
