CU-5c-1975D-01 Cud

Description

Leading the documented cud sequence for the 1975-D Jefferson nickel, CU-5c-1975D-01 records the first rim die fracture cataloged for this Denver Mint issue, with the cross-reference JNC-75D-4 in the Jefferson Nickel Cuds registry confirming independent documentation. Denver's 1975 nickel production totaled 401.9 million pieces, a peak-era output that ensured dozens of die pairs were in active rotation throughout the year. The mid-1970s represented a period of particularly high coinage demand as the economy dealt with stagflation and the public hoarding behavior that periodically depleted coin supplies from commercial channels. Each die pair in service might strike several hundred thousand coins before retirement, and the rim -- where the die face meets the collar -- endures concentrated shear stress with every impression. When fatigue exceeds the steel's tensile limit at any point along the rim, a fragment breaks free, and subsequent strikes force planchet metal into the resulting cavity to form the raised cud. The JNC cross-reference number 75D-4 indicates this was the fourth Jefferson nickel cud documented for the 1975-D date in that particular registry, even though it carries the "-01" suffix in the Cuds on Coins system. This numbering discrepancy reflects the fact that different cataloging organizations may document varieties in different sequences depending on when specimens are submitted for attribution. For collectors assembling a comprehensive Jefferson nickel cud set, the 1975-D date offers multiple documented examples, reflecting the year's high production volume and the correspondingly high rate of die casualties.
