Description
When a section of die steel breaks away and leaves a void, the planchet metal that flows into that cavity during striking takes on characteristics worth examining in their own right, and CU-1C-1986-05 on the 1986 Philadelphia Lincoln Memorial cent illustrates this phenomenon. The zinc core of a copper-plated planchet is softer and more ductile than traditional brass, meaning it flows more readily into die voids under striking pressure. This enhanced flow produces cuds with slightly smoother, more rounded profiles compared to cuds struck on harder copper-alloy planchets from the pre-1982 era. Collectors preserving cud specimens from the zinc era should store them in chemically inert holders. CU-1C-1986-05 is cataloged under its Cuds on Coins designation as the fifth documented die break for this date. Struck at Philadelphia on copper-plated zinc planchets at 2.5 grams and 19mm.
