According to the Red Book - the 1868 in G-4 condition is valued at $20. I do not grade coins, but think this is at least in G-4 condition. Just the 3rd year of the "Nickel." Up until 1866, all 5 cent pieces were made of silver.
Will make a perfect gift for my grandfather! I don't think he has one of these but has a few perfect coins left over from his childhood, back when the coins were silver.
