<p>[QUOTE=&quot;jloring, post: 484414, member: 15518&quot;]Are the three layers the same thickness? I believe the copper-nickel layers are thinner, which would allow the copper to show through (as previously stated) if machined. Anyway, I don&#039;t think it was machined (in a lathe anyway)... there does not appear to be any circumferential tool marks.[/QUOTE]</p><p><br /></p>
