Sweet coin man, what a find!! I would keep it if you don't have to sell it but if you do I would imagine you would only get the gold value as that coin looks pretty worn.
You have 3.6 grams of gold there and at current gold price of ~$60(usd)/gram, that's a pretty decent return on your $5 investment :)

Thank you, I've decided to hang on to it. It might come in handy some day.
