RRDC-1c-1960-01 (SD) Cud

Description

Linked to the same die as RRDC-1c-1960-01 (SD), this cud entry on the 1960 Lincoln Memorial Cent Proof Small Date documents the advanced stage where a portion of the die — already weakened by the bisecting rim to rim crack — broke away entirely. A cud error occurs when a piece of the die separates completely, leaving a void that produces a raised, featureless mass of metal on every subsequent strike. The connection to a bisecting RRDC die makes this cud particularly notable: the full-span crack that originally traversed the die from rim to rim created a natural fracture plane along which the die fragment ultimately failed. Cataloged by Cuds on Coins with a cross-reference date of February 1, 2014, this variety resides on the Proof Small Date issue, meaning it was struck on specially prepared planchets using polished proof dies at the Philadelphia Mint. The proof format limits each die's production to approximately 3,000 impressions, constraining the possible population of this cud variety. Together with its companion RRDC retained crack listing, this entry documents the complete mechanical progression from bisecting crack to fragment separation on a single proof die — an uncommon pairing in the proof Lincoln Memorial cent series.
