I am contemplating a new addition to my collection. I have never bought a coin in any Mint State condition. I am just not sure what premiums go along with certified ms coins. The coin is a 1918 Standing Liberty Quarter in MS63 FH. The coin is certified by PCGS. I have the Red book and Blue book, but understand those are only guides for prices. I would look forward to seeing what most CT'ers think this coin is worth. Thank You!
