Mint-made errors

In numismatics Fehlprägung denotes a resulting unintentionally, incorrect coin. Some misstrike who have inadvertently passed the quality control and had got into circulation, have become sought-after collectibles. Misstrike can arise in many ways: for example, can get stuck in the die ring a coin in shaping and then twisted a second time or embossed added. It also happens that coins are minted at the wrong circles, such as a one - euro coin on the blank of a 50 cent coin. Error in the embossed image can also be caused by dirty stamper. If there is a break in the embossing stamp floor, so that is clearly visible on the coin as a raised line.

Comparatively often encountered " stamp twists ". This is to coins whose back is not properly aligned to the front, for example, a 50-cent piece in which the Brandenburg Gate on the page " lies " or is upside down when you turn the coin around the vertical axis. Must be distinguished from the oppositely directed imprinting, in which the back is purposely for vertical rotation on the head, as it ( eg France) was formerly in many countries of the case. In general stamp twists came earlier because of lower technical levels in the embossing process more frequently than new coins. Usually the image is rotated by a few degrees so that the Stempeldrehung not noticeable at first glance. The stronger the rotation fails, the higher the fancy prices that achieve such misstrike. A special case are Belgian euro coins, stamps where rotations occur so frequent that the prices for these misstrike hardly lie mostly above the corresponding nominal.

A known Fehlprägung is a 50 -pfennig piece from 1950, which at that time was accidentally struck in Karlsruhe still with " German Bank " countries and in small numbers came into circulation.
