Were you looking under Danish West Indies? Because that's what this is. My Krause shows a mintage of 121,000 and it's 0.1867 oz of gold. I'd say it's a great coin. I've never seen one and coins from more unusual places like this tend to have a premium. That being said I have no specific knowledge of this coin.
Value, you bet, it's gold, and a nice looking coin to boot. Coins are listed on the Numista site going for over $2,500. https://en.numista.com/catalogue/pieces17054.html
I checked out the site. Thank you much. Do you have any suggestions on where to sell coins and should I get it graded?
I don't sell coins, and have no idea about gold. Many auction houses will sell it for you, with a commission, or list on eBay with a lowest limit. As for having it graded, I would, but again, I've never had any coins graded, so the fee is a consideration. Good luck and let us know the outcome.
