<p>[QUOTE=&quot;rmpsrpms, post: 3504895, member: 31773&quot;]Yes, it indeed flows away, but not toward the center of the coin! To do that there must be some good reason for it. Filling a void in the die is a good reason, but it does not take metal from closer to the rim to do that. Local metal from the bulk of the planchet is sufficient for that purpose. To make metal flow inward, there must be some inward force. The force from the collar is not a net inward force, just a reactionary force due to the OUTWARD force from the strike. Equal and opposite, so the metal hits a wall when it expands to the collar, but the collar force doesn&#039;t exist until metal has flowed outward to meet it.[/QUOTE]</p><p><br /></p>
