tershaffer Valued Member United States 232 Posts	Posted 02/13/2011 12:39 am As I looks through Coppercoins.com, I see a lot of variations of mint marks, most just look like MD to me. Is there something in particular I should be looking for. Of coarse if it were a complete double it would be noticeable, but some seem real hard to differentiate between RPM and MD. I look for the flat doubling when I am searching, but it seems alot harder on these than lettering and such. am I looking for positioning, extreme raising of the additional marks or what? Here is an example I found tonight, which if were on lettering or date I would chalk it up to MD, but on mint marks I'm not sure? Most of the pics I see on coppercoins I would chalk up to MD.

tershaffer Valued Member United States 232 Posts	Posted 02/13/2011 12:45 am here is an example from coppercoins. I can sort of understand the the middle, looks a little rounded and raised, but the bottom marks looks like MD or plate splitting to me?

You can see the die movment lines in that area. kind of like another coin I found years ago that show the same affect on the lower edges of the devices: Note the lower lines formed on the under part of the devices from metal movement.

coppercoins Pillar of the Community United States 7629 Posts	Posted 02/13/2011 1:05 pm The first coin posted is coin wear. The ridge has been rubbed or scraped leaving a sharp edge that may appear to be doubling....nothing else. The next coin posted is a repunched mintmark. There are raised areas that are separate from the mintmark in the field corresponding to a light repunching to the southeast. I am not sure how "many" of the listed repunched mintmarks could look like Machine Doubling. The difference between the two is rather obvious with a little experience and study.
