<p>[QUOTE=&quot;mkwelbornjr, post: 1356777, member: 17034&quot;]Still, US Mint uses the term UNC loosely.&nbsp; Coins in bags and UNC commems are produced using entirely different processes.&nbsp; With many commems and I believe with some of the Silver Eagles...the blanks for proof and UNC are the exact same blanks.&nbsp; Both dies are prepared with the same care...except the UNC version is essentially a Matte Proof...where the entire surface is blasted...not just the raised relief.&nbsp; The US Mint has started polishing the raised areas of proof dies with a laser which eliminates the need to mask out the rest of the die.&nbsp; The laser gives the frost that sparkling look like on the reverse proof.&nbsp; The UNC dies used for commems and eagles which aren&#039;t bullion quality are proof dies that are frosted over completely but not using the laser technique.&nbsp; The US Mint also has used the term Matte for some recent special issues as well.&nbsp; </p><p><br /></p><p>Look at a Chinese Panda...the UNC version is very much proof-like as well.[/QUOTE]</p><p><br /></p>
