From what i can tell, it looks like a MD coin, look at the top of the 9 and mint mark, notice how flat the devices are?, RPM expands the devices, so would true doubling,it does not reduce the devices as your coin shows, there should be a split or what is know as suriffs, on the device which a true RPM, or doubling would show......
I would like to apologize, to Hahnstein, i spelled the word suriffs wrong, the correct spelling should be"SERIFS"......
