This ring is made from an extremely rare, original "crest" key from Lincoln. I've been constantly searching for and buying keys for over three years, and this is the only key of this kind I've ever seen. The Lincoln font on the inside looks like a 1950's style. Like all of our rings, the brass key has been hand-hammered, hand-polished, and powder-coated (a clear polymer layer). Wearing a very unique piece of automobilia history like this is not an opportunity that comes up very often!
