Caught a Feb 2020 post of similar coin the author posted showing doubling primarily on date. After checking my 86 Ellis Islands found this and paused.
Coop am not convinced op's (Feb 2020) coin is wholly Strike Doubling
His pictures left out clear closeups of notching, perhaps example pics may better give cause to further examine his. I find similar doubling on 2 proof issues in my stack but not as pronounced. Am attempting to locate identical die markings on the 3 similar coins.
Hypothesis - hub doubling, then the proof die used later for circulation strikes? Its the 1 and the 9 that caught my eye.
Coop, need your analysis on this one. Thanks.
