Record 2 1997-01-31

English

Subject field(s)
  • Coins and Bank Notes
  • Numismatics
  • Coining
DEF

A thin and sharp upraised flange appearing on a coin where the rim (n.) meets the edge (n.); the excessive pressure between the dies and the collar during striking forces the metal to the limiting confines of the collar die, sometimes squeezing a tiny amount of metal past it.

OBS

A special rim, the wire edge is given to a coin either by accident or by design; unless clearly obvious, an accidental wire edge is not considered as a mint error.

OBS

Since "edge (noun)" is sometimes used instead of "rim (noun)", it is why "wire edge" and "knife edge" are used as synonyms of "wire rim" and "knife rim".

OBS

See related terms: rim (noun), edge (noun), square rim.
