CU-1C-1978-09 Cud

Description

Numbered CU-1C-1978-09 in the Cuds on Coins catalog, this variety skips ahead from the preceding entries to document the ninth confirmed rim break on 1978 Philadelphia Lincoln Memorial cents. The gap in sequential numbering between the sixth and ninth entries indicates that CU-1C-1978-07 and CU-1C-1978-08 exist in the broader catalog but are not included in this particular grouping. The ninth entry adds to an already substantial cud census for the 1978 Philadelphia date, confirming that at least nine distinct working dies suffered terminal rim failure during this year's production campaign. Each die's failure event is independent — occurring at its own unique angular location along the rim, at its own point in the die's service life, and affecting its own subset of design elements. The identification of nine separate cuds provides insight into die longevity under production conditions: if Philadelphia operated hundreds of die pairs during the 1978 cent run, nine terminal rim failures represents a failure rate consistent with normal expectations for high-volume coinage production. CU-1C-1978-09 carries no supplementary cross-references from other attribution services, and its identification relies on the break geometry documented in the Cuds on Coins photographic archive. Philadelphia cents of this date lack a mint mark and were struck from the 95% copper alloy standard for the period. Attribution by Cuds on Coins.
