1973 Topps All Series Baseball Card Sealed Pack PSA 8 - Mike Schmidt Possible
1973 Topps All Series Baseball Card Sealed Pack PSA - Mike Schmidt Possible
Mike Schmidt is only found in the 5th Series and all series packs.
Any pack is that is not designated as 5th series or all series does not have a possibility at a Mike Schmidt rookie.
1973 packs that do not have a designation are usually 4th series packs.
4th series is the worst series and sellers don't want to advertise their pack is a 4th series, so they ask PSA to leave it blank.
