Hi There!! This listing is for a Half Dollar Coin Ring Center Punch kit. The kit comes with 6 spacer rings for the Dime, Penny, Nickel, Quarter, Golden/Presidential Dollar Coin, and Canadian large penny 25.5mm!!!!! Certain dates vary in sizes on the large penny. The punch body is fitted to the 50 cent coin and comes with 2 punches and die sizes of 1/2" and 3/8"!!! The punches will have a 1/2" shank. The punches are made from O1 Tool Steel, 2 inches long. Hardened, and hollow ground, and has a relief, to make it easier for punching and to get the coin back off. The die is also Tool Steel, hardened and has relief , so that the blank falls out. This is an aluminum body and guide which is JUST A HOLDER for the the tool steel punch and die. The aluminum body and guide, guides the punch to the die and keeps the spacers and coins center for a perfectly centered hole each time!!!! Overall height is 2-3/4" with a coin. The O.D. is 1-5/8. This is to be used in a press only. Hammers ruin punches in a very short amount of time, no matter what, so this will VOID the warranty, no exceptions. Thanks for your business, and have a great day!
