<p>[QUOTE=&quot;Oldhoopster, post: 3938975, member: 84179&quot;]The edge pics are indistinct, but you should look for the “punch and tear” characteristic.&nbsp; When a planchet is punched from a strip, the punch will initially cut through the metal, but as it gets most of the way through, the remaining metal will tear.&nbsp; This will result in the edge having a partially smooth surface and what appears to be a torn surface (I’ll leave it to the metallurgists to provide a detailed explanation).&nbsp; This is a good way to distinguish between a coin that was ground vs a true clip that doesn’t exhibit the Blakesley effect.</p><p><br /></p><p>Also, look to see if there are any striations or displaced metal pushing up along an edge that would indicate abrasive grinding[/QUOTE]</p><p><br /></p>
