igwt79 Pillar of the Community United States 1464 Posts	Posted 03/14/2024 6:43 pm @Sannys25 you got it! Definitely Machine Doubling. I have a philadelphia 72 LMC that is very similar. Report this Post to the Staff

Brandmeister Pillar of the Community United States 6506 Posts	Posted 03/14/2024 7:41 pm There are two big clues. The first is that the mint mark and lettering show the same phenomenon. The process that produces mint mark doubling (repunching) is separate from the process that produces doubling on the other devices (die doubling). It is quite unusual to see them both on the same coin. The second clue is that the doubling reduces the size of the parent device. The metal to create the Machine Doubling comes from the device itself. A true doubled die has normal devices that have additional metal. Report this Post to the Staff
