<p>[QUOTE="352sdeer, post: 3504297, member: 91351"][USER=112]@GDJMSP[/USER] okay I took a handful, about 50 of nice clean Gem BU Lincoln cents from the sixties and looked at them under the trusty Swift stereoscope at 10x low and behold I see flow lines in most of the cents. After closer inspection at 45x it’s a hole other world but it’s clear to me that your theory has merit the metal appears to flow to the middle in most of the coins inspected. The rim being some bone of contention but it’s clear that the material in the finished coin rim came from the upset that has been put in the planchet. If anything there is excess material that has to flow away from the rim at the time the coin is struck and it kinda looks that way in some of the coins I looked at. All I know is this all takes place at high speed and we can never actually know how it happens we just see the end results.</p><p>I agree with you Doug.</p><p>Reed[/QUOTE]</p><p><br /></p>
