<p>[QUOTE=&quot;Conder101, post: 4700727, member: 66&quot;]Burnished is a VERY tricky word and can mean several different things&nbsp; At it most basic Burnish means to polish by rubbing with metal.&nbsp; </p><p><br /></p><p>A coin that has had rough surfaces smoothed by rubbing with a metal tool are said to have been burnished.&nbsp; This is bad.&nbsp; </p><p><br /></p><p>Planchets, after annealing, are cleaned by burnishing.&nbsp; They are tumbled with cleaning compounds and tiny steel balls to polish and smooth the surfaces.&nbsp; Proof planchets are tumbled longer and possibly with other compounds to give them a more polished surface.&nbsp; </p><p><br /></p><p>Then there are W wintmarked silver eagles which are called Burnished,&nbsp; They have an unusually whiter color which the mint says is because they are struck on burnished planchets.&nbsp; Which is meaningless because ALL planchets are burnished. I don&#039;t know exactly what they do to get that whiter color, but I suspect it is NOT by burnishing.&nbsp; I suspect a fine sand blasting or picking of the planchets pre strike.</p><p><br /></p><p>So a &quot;burnished&quot; silver eagle is good, a &quot;burnished&quot; circulation strike coin is bad.[/QUOTE]</p><p><br /></p>
