This is a coin that has been cut by hand and engraved into the shape of a cute little platypus! We cut our coins entirely by hand with a jewelers saw. Later we engrave the fine details into them. The one pictured is cut from a quarter. So the dime option will be a very very small pendant. A 20" thin chain will be sent with this order. However, if you would like a different size offered below please message us immediately after ordering. We offer various chain sizes from: 18" thin 20" thin 24" thin 20" thick 24" thick Key Chain Adj Black Cord
