Nice struck through error. I recalled seeing an 2017 Frederick Douglass ATB quarter error (PCGS slabbed) with a magnetic washer still stuck onto it. https://www.pcgs.com/cert/36402700
The washer looks raised and then every once in a while it looks recessed, either way a strike thru. Is that number 2?
Train wreck Can’t imagine the die was ever the same after that I wonder if any additional struck coins might show a weak circle
Very nice example. I imagine it happens more often than we think, but they don't make it out of the mints.
