PROCESS FOR THE PRODUCTION OF COIN BLANKS

摘要

A process for the production of coin blanks suitable for minting into coins includes providing metallic core pieces, each core piece having opposed, substantially planar faces and a common side edge. The core pieces are loaded into a perforated container which is placed in an electroplating bath. A metallic cladding is placed on the core pieces, while moving the container angularly about a horizontal axis, until the metallic cladding has a thickness of at least about 0.05 mm on each face of each core piece and a thickness of at least 2 to 4 times the face thickness on the side edge of each core.
