A friend sent me the link: https://www.ebay.com/itm/234623233755?hash=item36a0a26edb:g:pWAAAOSwg4Riz4bR Obverse and image of the "S" relative to known genuine positions/ shapes: And the reverse and VDB over a known genuine example:
VDB is obviously wrong, there's a regular 1909-S with MM in that position, so my first thought is an added VDB. The whole coin could be fake too of course. I wonder if a previous owner scratched the X through the reverse because they knew it was fake.
