Coin blank

from Wikipedia, the free encyclopedia

The coin blank , also Ronde or flan (chopping schroten =, part, separated, punch), the embossed metal piece to the embossing of coins is used. It is made from the zain . As a metal disc, the flint was previously separated from the zain with the piece scissors and then processed into a coin plate.

Flint defects

Various errors can exist with the coin blank that cannot be remedied by the subsequent minting process. Unevenness in the surface that is so deep that it still leaves flaws after the embossing is possible, or the end of the zain , where the planes at the end of a zain sheet are no longer wide enough to be fully captured by the die.

A distinction must be made between blanks and defects that only arise as a result of incorrect minting in correct coin blanks, such as a double strike by hammer minting.

In ancient times, planets were also often of different thicknesses. This regularly led to embossing weaknesses in the thinner area of ​​the flint. In the extreme case, the flint in this area remained completely undesigned due to the embossing. These errors are therefore a combined cause of planar defects and incorrect stamping.
