Ring embossing
The ring stamping or stamping in the ring is a method of coinage that is almost exclusively used today . With ring minting, the coin blank is centered in a solid metal ring during the minting process.
This lateral limitation and the associated prevention of the expansion of the coin metal enabled completely round coins to be minted for the first time, which at the same time can have a slightly raised edge ( edge bar ) and an edge inscription without additional knurling . The edge embossing made possible with the new technology is not only difficult to forge; they also increase the security of the coins circulation, since the filing of metal on the edge of the coin is very easily noticed. The edge rod is often followed by a pearl circle on the inside .
Ring embossing is an invention of the French medalist and die cutter Jean-Pierre Droz (1746–1823). Its prototype of a functioning embossing machine had a six-part embossing ring.
The ring embossing was used for the first time in the new Soho Mint . In Germany, Prussia systematically promoted the spread of ring coinage through the Zollverein since the middle of the 19th century.
