I agree, the pics aren't the best. But having a light at the proper wattage and then using no flash may work better.
Ummmm the "71" at the bottom appears to be clipped, so does the the "S". I think, with the pics provided, its Machine Doubling.
Others will chime in but this is my opinion..... Typically if it is an OLDER, pre-1990's DDO, all the devices and letters can be doubled, but its rare to see the mint mark doubled. DDO's and DDR's - the doubling is at the same height as the original device (letter or number) or ADDS to that letter or number, making it wider, fatter, higher or otherwise. Machine Doubling cuts into the device and may remove portions of it. I use this site for the "classic Machine Doubling" pictures.....
