1999-D Rhode Island quarter, with DC logo counter-stamp

Genuine US Mint 1999-D Rhode Island state quarter, privately counter-stamped with the designer's initials ("DC" circle logo).

At the time these were designed and minted, the US Mint's policy was not to include the coin designer's initials on the coins. Only the US Mint sculptor who finalized the design has their initials on them. Daniel Carr designed this coin for the US Mint in 1999 (and the design was actually minted in 2001).

Since the coins never originally had Daniel Carr's initials, on the occasion of the 25th anniversary of designing them (in 1999), coins acquired by Daniel Carr in 2001 are being counter-stamped with the round "DC" logo in 2024. A special backing die is used to reduce distortion of the Washington side opposite the location of the counter-stamp.
