<p>[QUOTE="Hobo, post: 347825, member: 11521"]It is called "Blakesley effect". When a clipped planchet is struck there is no metal to be forced into the collar at the clip. Directly opposite the clip the forces on the metal at the collar are reduced due to the clip which results in weakness in the struck coin in this location.</p><p> </p><p>That is a cool find. Probably not worth a whole lot but cool none-the-less.[/QUOTE]</p><p><br /></p>
