The coin looks be in good shape. Assuming it's real, with the gold price at $2685 this weekend, you are probably looking at a minimum value of $800. Possibly over $1,000 depending on its condition which unfortunately is impossible to determine with photos. First, make sure the coin weighs around 8.36 grams.
High-value numismatics such as your specimen should be appraised, graded, and slabbed by a licensed coin dealer. It will be easier to sell and give you a real idea of its true value. Of course, the coin dealer may offer to buy it from you outright, albeit at a probably reduced price. Find a coin dealer licensed by PCGS or NGC. Avoid pawn shops unless they are licensed by one of the two mentioned coin grading services.
