no idea wht these are going for ?
A silver coin in pristine/great condition will fetch 2.25 to 2.75. Even more if it is ANACs graded at ms 68 to 70
A brass will fetch 1.2 to 1.3. Again even more of me 68 to 70.
Overall it is nice to grade your coins. But if the grades aren't decent you might be looking at the same price as ungraded.
