But this specimen may appear to have some doubling on the reverse on the letters "U" and "R" in the word "Quarter" and the left side of The eagle's wing. Check it! Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 11/10/2021 11:27 am Machine Doubling is not actual doubling of the devices, but a reduction of the devices that area on the coin, removing the contour of the devices. This can happen in one or more directions after the strike, depending how loose the machine is. Single direction Machine Doubling: Two different directions: Where dies the contour go? It is pushed aside, often making the devices taller: Even doubled dies can be affected by Machine Doubling: Note the dates on this 1969-S DDO-001? You see the hub doubling present. The yellow arrows are pointing towards the MD on this doubling die. Again note that the doubled die has the hub doubling on the die, but right after the strike, the machine altered the devices. So Machine Doubling is not a doubled die, as doubled dies are on the die. Machine Doubling is damage to the fresh struck coin, right after the strike.
