This is a nice high grade piece that is clearly double struck. It weighs 26.8 grams and looks like it may be overlapped at approximately 6 and 12 o'clock, but I'm not sure. I can't scan the edges. Is it possibly genuine?

It looks very nice. Is it an UNC?

It may be Unc., but I would grade it a choice AU because of the bagging or handling marks on the portrait side.

The coin looks very nice - die designs are correct based on a rather quick review of style.

I would suggest that SG is needed as a minimum and that only XRF can make the final call. I have seen modern Numismatic Forgeries that were double struck to cover some of the die problems. A double struck coin always needs extra scrutiny before accepting it as genuine.

Thanks Swamperbob. I had thought about sending it to a TPG, but I don't think they are that thorough at authenticating these types. I hate slabs on top of that and own very few.

You are absolutely correct about the TPGs - they do not do Specific Gravity. They also do not even WEIGH the coins. So I would not trust any of them to authenticate this particular coin. You actually need to become an authenticator yourself.

That was a primary issue in my book. Until all collectors become authenticators for their own selected series of coins - fraud will abound.

Collectors must WEIGH, calculate SG and check visual designs on ALL of their coins. Until that happens forgers will have a wide open field.
