STAMPING DIE FOR COINS OR MEDALS, METHOD FOR MAKING SAME AND COIN OR MEDAL |
摘要 |
Die for coins or medals, comprising a hardened surface in which a pattern of indentations is produced by means of a laser beam. This pattern alone determines a motif that is transferred into the coin during its minting. All indentations have substantially the same height and depth measurement, and the pattern in question is obtained by varying the density.
