I'd like to chime in this discussion with a question. I know they produced an "update" version of these stamps with new players and maybe players who were on new teams (not sure about that). For the most part, the updated players were made available in team sheets which had the perforations.
Back when I was collecting these as a kid in '72, I wrote the company who produced the stamps and requested some replacement stamps and they sent me unperforated versions of the replacements AND unperforated versions of the new players. I am fairly sure these unperforated versions are scarce compared to the perforated versions, but I wondered if there were concerns among collectors about whether they were just trimmed versions of the perforated versions.
I still have the envelope my were shipped in (the mailing label was filled in by me, so I can see my 12 year old handwriting) and I have about 25 regular stamps and 25 new player stamps. I know I never trimmed the stamps I have, so they were likely cut from sheets by the manufacturer.
Just curious if anyone is knowledgeable about these.
