Abstract
A process for identifying an embossed image of a coin in an automatic coin tester, in which a coin is moved to an image receiver and a light source, the image receiver picks up at least one image of the embossed image of the coin, and a validation device compares the image to a first reference pattern to find out whether the first reference pattern is contained in the image which was picked-up. If the first reference pattern is contained in the image, the validation device determines whether a second reference pattern is contained in an area the position of which is determined relative to the position of the first reference pattern, the validation device producing a genuine coin or counterfeit coin signal for the coin depending on the coincidence of the image with the reference patterns.
