[QUOTE="treylxapi47, post: 1801266, member: 41863"]Ok, I have been reading the chapter in The Experts Guide by Q. David Bowers on proof coins and I had some glaring questions jump up at me. How are proof dies polished to the point where you cannot see any hairlines in the fields? In reference to the first question, if you had a proof coin that exhibits 'shiny' portraits and devices versus the same in a cameo format, how do you polish said portraits and devices without seeing any hairlines. This is mainly a question on proof coins where the whole coin was polished and was a shiny proof instead of a frosted proof coin. My last question for now is if the mint was able to achieve such a feat, then I would assume it would be easy enough to replicate a similar effect on the coin itself to where a cleaning could 'enhance' a coin and be unnoticeable to all but the most savvy of collectors. Is this not a correct assumption? I mean I guess it wouldn't exactly be easy, but doable all the same.[/QUOTE]
