Die Caps:
Partial (off-center) Die Caps:
Definition: A partial die cap begins with a coin that is struck off-center and sticks to either the hammer die or the anvil die. It is then struck into the next planchet, leaving an “aligned” partial brockage (see aligned partial brockage). Partial die caps involving the hammer die are much more common than those involving the anvil die,since the latter tend to be scraped off by the ejection finger or lifted up by the top of the collar.
This Lincoln cent is a partial die cap of the hammer (obverse) die. After it stuck to the obverse die it struck one planchet and fell off. The raised details of the reverse design are flattened and expanded from that second strike.
