This concho is made from a Roosevelt dime silver coin from before 1964. The design is a torch. The size is approximately 17mm. As it is an old circulating coin, there is some wear and tear. The screw is M4 and about 4mm long. An 8mm screw for thick leather is also included. It can be attached to a large jumper snap. The photos are from previous stock. The item will be shipped as a similar product. Thank you.
