This is a US Half Dollar 50-cent Eagle concho. The size is approximately 30mm. I have processed this using circulating currency. The screw size is M4, and the length is approximately 5mm. I will also include longer 8mm screws. Please use these on thick leather. Compatible with large jumper snaps. The photos used are from previous listings, and the product shipped will be of similar quality. The year may vary. Shipping will be via Yu-packet Post Mini. Thank you. If you need multiple pieces, please check the stock beforehand. I will deduct shipping costs for the second item onwards. I will relist them as a multiple-piece set. #Leathercraft Material
