Proof coins. Any collector at the hobby has at one point added a proof coin to their holding. A newer Washington quarter or modern commemorative. Perhaps it's a silver Roosevelt dime graded PF64 CAM. Yet how often, if at all, do we think of proof coins beyond those bearing the image of a President? As you must surely be thinking of them now, going a step further, does deep or ultra cameo enter the mind? This is the discussion of the week, pre-1900 deep cameo coinage. Enjoy!
