Depends if there is jeweler mark, who made it, how many karats, Ect. Half the time most gold will be worth it's weight.
Unless it has an O mint mark, about $300 for its gold content. If it's a 1909-O, it's worth about 2.5X as much as a collectible coin.
You need to provide a denomination, an estimate of condition and a mint-mark (if any) for us to accurately evaluate your coin.
depending on condition, about $300
