Foreign coin rings are can be made of any non-U.S. silver coin. Most country has minted some form of silver coinage or bullion and I search for any coin large enough to craft into a ring. Nearly all silver coins are mixed with some other metals to give the coin more durability. For my U.S. coin rings as well as any foreign coin rings I make, I try to use coins with a higher silver content. Only a few foreign coin rings are listed in our store but most countries and years are available upon request by submitting a custom order quote request under the (contact us) page.
