Well, an uncirculated one would sell for whatever 1 ounce of silver is selling for, today about $27. However you say with proof, I'm not sure what that means, if you mean it has some sort of certificate of authenticity or it is a proof coin. A proof coin will have mirror like fields (parts of the coin with no design) and an uncirculated coin will have shiny, but not mirror like fields. A proof coin is more expensive and would sell for around $70.
The best place, and most convenient for you, would be to go to a coin shop and offer it to a dealer. You will not make as much as if you were to sell it online, but when you sell it yourself you are accepting the risk of losing the coin in the mail, having an unsatisfied buyer, BUT you will more money for it.
These sell regularly at coin shows for a dollar or less.
