ADC-1c-2000S-01
This is a modest die clash, but what qualifies it as an ADC is that it is found on a proof coin.
The 2000-S Lincoln cent shows a dual set of clash marks on the obverse die. The clash marks are not that apparent on the reverse die and may have been affected by the frosted appearance applied to this proof coin.
This coin was encapsulated by PCGS and is in the private collection of Neal Burnett.
