 to CCF. I believe that is MD=machine doubling,because the letters are incuse that's why it is MD. If the letters were not incuse it might be a doubled die. Use the search box upper left of page for more info. We get this type of question a lot about a possible doubled die on the ATB Quarters. John1  |

I thought I had a thread about this subject, but this thread covers where the real DDR's are on the reverse of the ATB Quartershttp://goccf.com/t/313322#2664721This will show where to look on the quarters. No DDRs are found on the incuse design on the outside edge of these quarters. 70% of the time, they are Machine Doubling. Because the devices are incuse on the coin, these devices are raised on the die. The slightest MD alters these devices before/during/after the strike. They are weak most times, other times strong, but they are not a DDR. A memtioned above, the DDR's are found in the central areas of the design on the obverse or reverse on the 50 States/states/ATB quarters. |

In the 5th and 6th image, it looks like multiple strikes, with each strike higher relief than the others until you reach the main strike. Pretty characteristic of Machine Doubling. Those first images had me stop for a second though. |

whatever you do keep that coin. If you ever see another and can match it same die chips and die scratches you got money because according to the coin experts here Machine Doubling can not identical. Each one is unique and different from any other one. Am example I got three 2017 Jefferson nickels with exactly the same Machine Doubling. <---- lots of sarcasm in that sentence. Just recently a guy posted a penny on here where he was told multiple times it was "MD" he sent the coin to wexlers and it was attributed as a doubled die 2020 1¢ WDDR-001.After attribution people who said it was MD blamed the picture for everything from not good enough to bad. In wexlers letter he (wexler) said it was the photo that helped him determine it was a DDR. I suggest you send it out to Wexler or someone who deals with doubling on coins because if there is a chance its something new you should get the credit for it. I got a 1988 penny with a raised perfect circle on Lincolns neck and cheek. was told post mint damage. Ya, post mint adds metal to the coin in a perfectly round & raised circle http://goccf.com/t/381270 here is the link to that post. I'm still wondering how that metal got raised after the coin was minted. Wouldn't post mint damage only take metal away. move it or bend it? so have someone look at it and don't discard it. |
