Reverse is lucky to be a PO01 and the price is that for a decent AG-3, but you can say you get a high quality scan. Does the original sandpaper come with it? https://www.ebay.com/itm/1893-S-Bar...445910&hash=item56c0cd56ba:g:1eAAAOSw2xRYbssr
Yes, that is definitely a PO coin. The back is almost blank from wear! At that point, I think $5-$6 would be a generous price- not $99.
What about this 1897s???? https://www.ebay.com/itm/Special-18...456604?hash=item4b5ddf35dc:g:T5YAAOSws0pcN3sn
