Collecting coins is not see at 100x or more. Collecting coins mean 25x and not more 50x. If you bring me the coin in lab and we look at 1000x or more nothing will fit with mint design. An error or variety is attribute at 25x, only some cases of planchet at 50x. the angle, light, etc and the calibration of your camera and the computer play a lot.
Your coin is an end of the life of the Die, also SSP post same kind of coin. Those small differences are in the Mint parameters. Thing after 200k KM your car will run same like at 5K KM?
