No wear on the coin it has not been used. None of the coins designs , numbers ,letters show any sign of use.
A certified example has a average current value of $700.00.
You will have to take the coin to a collector or coin dealer so someone can see it. Just because it is from The American Historic Society does not mean it's a Mint State coin. I have seen many coin sets from this society, so don't be surprised if they are not uncirculated coins.
