The Ruben Dario 50 cordoba gold coin is one troy ounce of gold, and has a minimum value of the current spot price (check KITCO for spot price). In spiffy condition it may be worth a slight premium over spot. If graded and slabbed by NGC it could be worth up to 20% over spot.
The value is basically the "spot" price of gold. You may be able to get some small premium over the intrinsic value of the gold if it catches a collector's fancy, but don't count on it. If you want more than the "melt value" of the gold, you will probably have to sell it on eBay or some other private sale venue. Coin dealers will only offer a wholesale price, which will be the gold value, or maybe 1 or 2 per cent below the spot gold price.
