because of the uniformity of the scratches on a cleaned coin, it is doubtful you would wear enough of them off that way to retain AU and may have to drop as far as VF to get a clean grade again..
The type 1 was one of the first coins I added to my collection. I've upgraded it twice since then, with all 3 still in my collection. My first one (obverse only) 1st upgrade..... Last upgrade.....
@mrweaseluv good luck with the auction. BTW, what do you think of this coin (Full Head, Full Shield, no apparent wear); PCGS screwed me on this one. If I still had it I would ask you if you were interested:
