In following the advice from some members, and I do think it is good advice, I am growing my resource library. Can someone offer their opinion on good reference books for:
1. Seated liberty series, with a specific interest in half dimes/dimes
2. Mercury dimes
3. Grading standards for US coins with hopefully photographic examples across the grades and key areas to examine for each
4. Forgery detection/coin doctoring
I have been reading reviews on several, and as usual they seem to be all over the place.
