This is a US $1 Susan B. Anthony dollar coin concho with a moon and eagle design. The size is approximately 27mm. I purchased the coin on Yahoo Auctions and processed it myself. The screw size is M4, with a length of approximately 5mm. An 8mm length screw is also included. Please use it on thick leather. Compatible with large jumper snaps. The photos are from a previous listing, and the item shipped will be of similar quality. Shipping will be via Yu-Packet Post Mini. Thank you. If you need multiple pieces, please check the stock beforehand. Shipping costs will be discounted for the second item onwards. I will relist as a multiple-item set. #Leathercraft Material
