(only they use a rotating lap because the fields are the high portions)&nbsp; You don&#039;t see the hairlines from the dies on the fields of your proof coins do you?&nbsp; All polishing is done using abrasive grit, the result is just a matter of how fine the grit is, get it fine enough and you can&#039;t see the polishing lines anymore.&nbsp; The lines are simply finer than the resolution your eyes can detect.&nbsp; For those that have polished scratches out of their slabs, the final grit used in the plastic polishing is probably about the same as the starting grit he used on the coins.</p><p><br /></p><p>This is probably how they used to make the &quot;California prooflike&quot; Morgans.&nbsp; Polish the fields like this and then artificially frost the details.[/QUOTE]</p><p><br /></p>
