<p>[QUOTE=&quot;Cloudsweeper99, post: 771740, member: 3011&quot;]It&#039;s a good question.&nbsp; Proof coins are made with special dies that are polished to a mirror-like finish.&nbsp; The coins are minted using special hydraulic presses that operate at slower speeds with more pressure than regular business strikes.&nbsp; I think they may also be struck twice to achieve the mirror effect in the fields.&nbsp; I also believe the planchets are prepared with a special wash.[/QUOTE]</p><p><br /></p>
