1831 Bust Half Dollar AU-details sells for $4,550.00.....?????????

The variety seems fairly common, a high grade AU with green verdigris on the reverse on the letters "O" and "R". Coin was sitting at $200 with 5 seconds left in the auction until (2) bidders raised it to $4,550.00..........What did these two bidders see that I didn't?:

A seller who is peeing down both legs now.
Looks like O.120 which is R6

o-120 has a bulge in the obverse field and a spike on the reverse highest olive leaf.....This coin shows neither.
Hard to tell from the seller’s pics
1st I thought it was 2 people messing with the buyer, than I thought maybe they thought it was the o-120, than I thought maybe it was a circulated proof.........I have a feeling it's none of my thoughts, maybe it was the ambien I had last night. lol
It would take two guys with really deep pockets.

Ironic.
If I were the seller I would refuse to take payment via PayPal. Imagine eating the fee in this case, for the buyers mistake when they inevitably force a return, if it's not anything special.

It's an R6- O.120. If genuine.

For those interested, an Overton-120 is described as having, "a tine off the upper olive leaf and a large die bulge in the left obverse field." As can easily be seen, on this well worn example, the obverse bulge and reverse tine are prominent:


The coin in the listing has no bulge on the obv nor any sign of the tine on the reverse:


Plus the star #13 in the first coin is near the top of the segment and the seller's coin shows it between segments
BHNC #203
Here's an overlay using a high grade O.120 (AU58) from PCGS and the ebay coin. (FWIW, overlays are rarely perfect due to imperfect camera angles, coin rotation, etc.)
Again, I'm not saying it's genuine.

Hopefully, this side by side will clear this up:
money to burn (not ours either)
Perhaps an earlier state of the dies?

That's what I was thinking. That "spike" could certainly have been acquired after some period of use without it...and a die bulge just screams "old die". All positional information seems to indicate it COULD be the rare variety.
So, to prove it isn't, you'd need to find a different Overton that DOES match this coin....or assume it's a new variety, (which would be even a better deal, me thinks). I don't have the book, or background, to prove anything myself.
To each his own.
Reminds me of the peak years on Ebay (2003 to 2005).
