In my personal opinion your coin looks like it was whizzed...
I come to this conclusion as a number of years back I submitted some nice Bust Halves &
Morgan dollars for Certification, coins I purchased at Coin Shows before the Internet age...
One of the Bust Halves that I purchased as AU+ (and looked like your coin), came back "whizzed to look unc.", and others came back as " cleaned and Artificially Toned"...
Prior to this, I never knew what a whizzed coin looked like, now I will never forget...
