<p>[QUOTE=&quot;physics-fan3.14, post: 4895664, member: 19165&quot;]Insider, I know you like colors so I circled what I see:</p><p><br /></p><p>Red: deep marks in random patterns, most likely contact marks (bag marks, etc - normal hits)</p><p>Orange: thin, whispy long lines, most likely from polishing, a wipe, or potentially cleaning (need to see the rest of the coin to confirm)</p><p>Purple: deep marks in what appears to be a regular pattern. Could be dentil marks (reed marks) from contact with another coin.</p><p>Pink: Long, thin, straight, regular lines. Potentially roller marks.</p><p>Blue: short, intermittent parallel marks. I&#039;ll be honest, I&#039;m stumped on this one. Perhaps seeing more of the coin might help.</p><p>Green: very small, random pattern, scattered across the surface of the coin. Three thoughts on this one, would need to see the rest of the coin and luster to confirm. First, and most likely thought, is some sort of planchet flaw. I&#039;ve seen the fields of coins where it looked like the planchets had been very roughly tumbled but not polished, and the force of striking didn&#039;t completely removed the roughness. It could also be something raised on the surface of the die - pimples from die rust that hadn&#039;t been removed. Depending on the mint, rust was a common issue. Third thought, it could be where some corrosion was starting to form on the surface of the coin, eating into it, and the corrosion was removed. I think this is the least likely, because it looks like contact marks are over the top of this area - removal of corrosion indicates it was conserved, and I would hope that a collector would not then cause a huge mark like that. </p><p><br /></p><p>Well, I&#039;m hoping I got at least some of them right!</p><p><br /></p><p>[ATTACH=full]1181358[/ATTACH][/QUOTE]</p><p><br /></p>
