If you could post pictures, that would be helpful.
Based on what you are saying, I would try to sell the
Three Cent Nickel for about 25 dollars and see if someone bites. The dollar piece, I would try to sell for about 7-10 dollars.
If I were you, why don't you try selling it at a higher price first and see if anyone bites. Just don't be that guy from a previous post who is trying to sell an American Silver Eagle for about $2500. You will lose your credibility.
