Message:: [QUOTE="GDJMSP, post: 2053063, member: 112"]Another nice original coin from a "broken" Proof Set. No problems, but it has some mildly distracting die polish lines on Franklin's bust. These are not hairlines as would come from being wiped or cleaned. These lines are common to this era of issue, as the Mint re-polished dies to try to keep them in service, as well as to maintain a Cameo effect - this coin does show some Cameo contrast on the Obverse. Small problem with that description, the cameo effect is not and never was created by die polishing. There have been several methods used to create it, sand/bead blasting, acid etching, and laser etching. But that's it. So there is no way those lines are the result of die polishing or anything even close to it. And until 1973 the mint never cared if all of their Proof coins had the cameo effect or not. Sure they created it on the new dies, but once cameo wore off due to strike wear they did not even attempt to renew the effect on the dies. They just kept right using the dies producing brilliant Proofs with no cameo. Once the dies showed sufficient wear over and above the loss of cameo, they stopped using them. Were Proof dies ever polished before and during this period ? Absolutely, but typically only to remove clash marks, and even then it was not always done. The Bugs Bunny Franklin is an example of that. Now you want evidence of this ? Buy a book, several of them, for that is where you are going to find it.[/QUOTE]
