You ask the strangest questions Don't forget to add a question mark at the end of your questions.. It looks like this - ?
1792 what? Not many US coins made in 1792, just patterns I believe. Also I think the dies may have all been hand made, meaning there couldn't be a doubled die.
It'll be whatever the highest bidder is willing to pay for it at auction. But to indulge you, given that it may be a unique and a perfect example, I wouldn't be surprised if it ends up to be at least in the 7 figures. This isn't a perfect comparison, but what would an authentic and sole surviving 1964-D Peace Dollar in MS-70 be worth?
Nothing because it would be a fake. Doubled dies come from hubbing and hubbing wasn't done at that time.
