The value can vary quite a bit, depending on whether it is a proof or business strike, and then upon the grade . . . probably anywhere from $300 to $2000. If the coin exhibits any signs of cleaning, all bets are off, and the foregoing range is substantially reduced.
Looks like a higher grade business strike, somewhere around MS65. Detail in hair is great; The reverse strike is wonderful. If there are no issues not visible in your posted pics, I suggest getting it slabbed. Retail price is in the $300-325 range. If it grades higher, that number will rise quickly. Again all prices and grade opinions depend on the coin being adequately represented by the photos.
