1891-CC $20 Gold Coin - Real Or Fake?

I must be remembered that all dates of U.S. gold coins, of all denominations, have been faked in the past.
Because it is a rare date, there is a much greater temptation for it to be faked.

Need much sharper focus pictures for this thread.

Needs to be checked accurately for weight.

If these OK,
then it needs to be checked with an XRF instrument. Go to a scrap gold buyer for that. If it turns out to be .900 fine, you must keep the coin, for further consideration. If it turns out to be .900 fine, it will be worth many times it's gold value.
The scrap gold buyer may well ask for a testing fee.

As noted above, on the OP coin the date details of the loops on the eight and bottom loop on the nine look off and position is not correct. I would guess only one set of dies being used for a gold mintage of 5000 coins as I could not fine any other position for the date or CC. The position of the CC is off when compared to genuine examples. The OP coin appears to be a counterfeit.

Genuine NGC AU58


OP Coin

Date numeral style does not match that on the known genuine coin. At that time they were using the same date logotype for ALL the dies, so the date should be the same on every die for that year. The 1's are too tall and thin, the inner loops of the 8 and 9 are almost round notovals as on the genuine.

Welcome to the forum!

100% fake. Heritage Auctions is your friend - search auction archives and look at images. Not only is CC in the wrong position, I don't think it was even taken from a real CC coin. The C's look childish. And where is the eagle's left wing? The date just looks silly. Hope you didn't pay real money for this. The cheapest real one on HA went for $4000, and that was AU50 repaired and whizzed.

Probably a fairly recent one (last ten to fifteen year)

Welcome to the forum. Unfortunately the coin appears to be a fake. The date, mintmark and reverse lettering all look off.
