8 Reales 1769 From Guatemala - Essayer P

I can't believe this coin is authentic! Theres jsut too many things wrong with it! Where do you start?

if you've already won it, can you still back out and not pay for it? even if the reason is valid?

sorry for asking, I hve no direct experience at all at ebay auctions, I ask a friend, who's the member, to bid for me and I did get stuck up with some fakes, part of the risk

The link was included in the original posting, below the photos. I am sticking to my belief that if this coin passes the SG test, it is real. MathieuMa, we'll be waiting on your follow up post when you receive the coin if you go through with the purchase.
SwamperBob, this woulod be an odd coin to counterfeit because you could only make one without tipping off the collecting world that you had a fake. Like a cob coin, there should not be 2 identical coins of this variety because of the random mis-strike on the perimeter of the coins due to planchet size. Anytime 2 cobs that are identical show up, they usually get noticed quickly and put in the fake coin databases.

jfransch Not quite sure the planchet variations here are as significant as cob pieces and I am not sure they would be correlated as easily as cobs are. If the forger is using an over-sized die pair in a screw press he could easily duplicate expected diameter variations and by extrapolation from known photos predict what the dental area should look like on sequential strikes. By offsetting each strike in a different direction he could make 4-6 coins easily and then sell them at 6 month intervals - each time making $200+. Of course once they get the dies right they could revert to an undamaged format and go for $600 each.

My diagnosis was actually based in part on the cracks visible at the top of the coin. They look a bit soft to me (a subject that has been published before) with a branching that should have been accompanied by die metal loss - but which seems to retain the central die metal fragment(s) without displacement. I was also rather concerned that the margins of this coin correlate too well to the Gilboy plate coin G-8-18e. It appears to be the same die pair with a few more chips as if it simply aged and more of the dentils flaked off as a result of perimeter cracking - but I believe I see matching damage to the right column just at the point where the ribbon tip makes its lowest pass over the column.

Duplicate damage (post strike) often proves forgery and if that ding is a struck/cast in feature it should be obvious in person.

I hope it is real and I hope more detailed photos especially of the EDGE will be forthcoming.

Would the seller agree to a contingent purchase of the coin was forwarded to say NGC?

If the coin is not real the dies are so well done that it would fool me in a picture. That does not automatically imply it is real just not clearly detectable in a picture.

I still have two concerns - the edge overlaps which I can see only one of on the third picture and the wavy planchet. With the better photos the die cracks look better.

Have you got a precise weight or SG?

Ah, cotton gloves ... I thought about those, but thought that old coins wouldn't need them (proper cleaned hand though are required) :)

The coin looks indeed great, and the mount mark is not that visible (could be worse).
I'll recheck the overlap and post a picture - but it's not clearly visible on the first position (should be somewhere on the first edge picture).
Actually the pattern is "less complete" on half of the coin - this can be seen by comparing edge picture 2 and 4.

I'll get precise weight tonight as well (got the scale with me, but not the coin).
The coin should be safe, as it comes from an Aureo sale (http://www.aureo.com/) - although some already saw fake coins being sold there (or on heritage)

Up :) In case our local specialist missed the update :D
Thx in advance ;)
