CU-25c-2006P-18R Cud

Description

Documented by Cuds on Coins as CU-25c-2006P-18R, this State Quarter cud variety appears on the 2006 Philadelphia Mint issue from the 50 State Quarters Program (1999-2008). The catalog number indicates this is the eighteenth documented reverse cud for the 2006-P date — a notably high number that reflects the massive production volume and large die population employed for this popular circulating commemorative program. A cud is a raised, featureless blob of metal that forms when a piece of the die rim breaks away, creating a void that fills with unstruck metal during the coining process. The cross-reference notation carries a date of February 13, 2021, indicating when this variety was documented or verified in the catalog. An additional diagnostic note identifies an obverse die chip marked with a "black arrow" designation, providing a secondary identification feature on the coin's face beyond the reverse cud itself. The State Quarters Program featured five different state reverse designs each year, and the 2006 issues honored Nevada, Nebraska, Colorado, North Dakota, and South Dakota, with each design paired with the standard John Flanagan Washington obverse. Struck in copper-nickel clad composition — an outer layer of 75% copper and 25% nickel bonded to a pure copper core — the coin weighs 5.67 grams with a diameter of 24.3 mm and a reeded edge. The combination of a reverse cud and an obverse die chip on the same coin suggests this die pair experienced significant deterioration, making both-side diagnostics available for confident attribution by cud variety collectors.
