Csgan, the coin in the picture you linked to is of a
silver dollar of 1799, as the link that points to the picture clearly states. All US gold coins dated 1799 have the same obverse design as the one I showed earlier, known as the "capped bust";
here is an example with the 1799 date.
The fuzzy and "slightly wrong" details on your coin, and the mismatching of obverse and reverse dies, are characteristic of the "Chinese fakes" commonly seen on the market in China and elsewhere.
Sorry, but your "gold coin" is not genuine, and in all likelihood not made of gold.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
