Master set question

[Bestdj777]

I am working on the Mantle master set. I used PSA's master set as a starting point then supplemented it in two ways. First, I went in to PSA's population report and searched for Mantle by name. Some of the rarer cards are not included in the PSA master set but can be found there (note, some of the multi-player cards will appear in the master set but not in the population report). Second, I went through the Sports Collectors Digest and viewed every entry from the relevant years for Mantle. PSA does not grade certain issues, and this was the only way to supplement the list. It might seem like a bit of a hassle but I really enjoyed getting to study the different card issues.

Despite all of this legwork, I am still finding new cards and variations, some through Al's incredible, yet costly (for me) knowledge of vintage Topps.
