More Information
Summary:The invention relates to a process for producing coins or tokens from metallic materials, with a coding composed of ferromagnetic material particles, small continuous holes being punched at equidistant intervals into a strip of coin metal, wire portions of ferromagnetic material being riveted into these holes, and finally coin blanks being stamped out of the strip, according to Patent Application P 3204393.7. The coding of coins is intended to improve their security of use in vending machines. A further improvement can be achieved if, in the said process for producing coded coins, there is used as a strip a layered material which is known per se for coin production and which has at least one continuous layer of ferromagnetic material.
