dollardude Valued Member United States 92 Posts	Posted 02/07/2018 4:14 pm Sooooo..... first off .....I already have downloaded and read the coin ID for dummies vol. 1 and 2.... I am still (and have been for some time) fighting to learn and recognize the difference between machine and hub doubling.... This is the latest one to stump me... at this point I am really just trying to learn the doubling... so I am not uploading full coin pics right now... Please offer your opinions on the doubling and so I can compare my notes to what you come up with... Many Thanks for helping me learn this! Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 02/08/2018 3:54 pm The coin is actually struck once on business strike coins. On Machine Doubling the devices are altered after the strike. So if it show doubling on both sides of the devices, the machine was very sloppy at this point. (moving in more than one direction) So all this was done in one strike. MD is MD. If can affect coins after the strike, during ejection or what else can happen. Still just MD.
