Scarcest Post 1952 Topps Regular Issue Card

[fkw]

I guess if it came in a pack it counts even though the Herre(a) is really just an overhyped print defect, and shouldnt be considered a part of the 1958 regular set....
if your counting print defects... any card from any 1950s-70s set printed with a blank front/back would be scarcer... and they came in packs too. or maybe even cards like the blue background 1958 Aaron would be scarcer too... but they are all just printing defects

If including any card listed in the checklists.... Id put the 1967 Maris Proof and 1977 Jackson proof at the top. But I ant no Topps expert

Anthony listed some pretty good ones. I would add the 66 Punch Outs ( not 67), 71 Rookie Artists Proofs and 68 Discs. But the original poster seemed to specify "regular" issues. The only issued Topps set I have been unable to complete ( 11 0f 24) is the baseball subset of the 1955 Hocus Focus issue. This too may not fit the intended definition, but was an issued set

I agree that it is a print defect that would likely get no traction in a modern issue, but it, the 57 Bakep and 52 Campos black star are all scarce necessities for a master set collector.

For Modern collectors try to get the listed 1980 Pryor no name card....much tougher that the yellow name variations for that year ( more print defects but all listed in SCD)

The 1990 Topps President Bush card or the 1984Topps Darryl Palmer card # 800 also come to mind
