<p>[QUOTE="SPP Ottawa, post: 8062891, member: 39508"]Larger clips can be very tricky, and they often have subdued Blakesley Effects. When it comes to clips, my eyes always go to where the rims meet the clipped gap, and they should dovetail in from the fields. On very large clips, the entire rim should taper into the clip. Here is a legit example (Canadian coin, but the process is the same).</p><p><br /></p><p>[ATTACH=full]1397647[/ATTACH]</p><p>[ATTACH=full]1397648[/ATTACH]</p><p><br /></p><p>Secondly, the Blakesley Effect is caused from a drop in pressure in the upset mill, resulting in a poorly formed rim. Seeing the rim flattened down to the point of touching the legend letters is not correct.</p><p><br /></p><p>For the OP's coin, I don't think it is legit. The rims where they meet the clip are really squared. The only time you ever see that, is when you strike an incomplete punched planchet and then clipped part pops out during or after the strike (like a 'football' clip). Then, in that case, there is no Blakesley effect.[/QUOTE]</p><p><br /></p>
