i agree. it does look polished. ...as for whether it ruins the coin or not... it depends. Most will consider polishing/cleaning of any kind to be 'damage' to the coin.
Wow, polished. I wonder if the polishing of the coin has made it look AU? Hard for me to give it a grade with the current photos. THe 1921 peace dollars have strike issues, so I'm not comfortable saying it AU, yet. Either way it looks polished, and that is not good. I would stay away and find another one. The 1921 peace is not difficult to find, just be patient.
Depends on your definition of "ruin". If that coin is AU (I cannot tell for the glare), it should sell for no more than an XF price when cleaned and probably VF as much as that has been cleaned.
This is definitely AU. Do not go by the seller's estimation of AU-BU, there is no way it is BU. Just look at the hair on the obverse.
If there is any doubt that this coin is polished, look at his other items for sale. He polished every coin. Run away, far far away from this coin and this seller!
I agree with ksparrow whizzed and ruined , too bad it's a key date , would of made a nice coin if he left it alone or had it done right . rzage
I cannot tell for certain from the pics, but given the apparently clean fields, I would also go with polished. The earlier comment of $10 melt is way off. It's still a 1921 Peace, no matter the treatment. If I watched the guy polish it, I'd still pay $50-60, and sell it for $70-80.
