Depending on the mint, and the condition, I show prices from $69 - $150 on average (these are excellent condition). You could however, have a coin in very good/uncirculated condition that could be worth more or less. One of the best places to sell is on eBay, where many people may be interested in your coin. These links below have more information on the possibilities of your coin...how many were minted, the designer etc. Let me know if you need more info.
