1875-P

Hub Combo: Type 1/1

This is the key date to the series. It is also essentially impossible. There are zero undisputed examples of the date. If one thinks they have a 75-P, even if in a TPG 75-P holder, it must be die matched so as to be proven not a mintmark-obscured 75-CC or 75-S. There is only 1 die combination.

Hub Combo: Type 1/2

This is the key date to the series. It is also essentially impossible. There are zero undisputed examples of the date. If one thinks they have a 75-P, even if in a TPG 75-P holder, it must be die matched so as to be proven not a mintmark-obscured 75-CC or 75-S. There are several die combinations so it is not as easy to prove/disprove the date as the type 1/1, however, proving the date is essential for proper attribution.
