<p>[QUOTE="jgenn, post: 2949565, member: 78525"]That's a big question but to focus on the part where the reeded edge is created you just need to know that a coin blank is compressed on its edge in an upsetting mill to create the raised rim resulting in a planchet. Then the planchet is placed in a collar on the coin press and struck between the obverse and reverse die. The pressure from the strike causes the coin metal to flow into the depressions on the dies and the inner surface of the collar. For the reeded edge design, the inner surface of the collar is engraved with those lines.[/QUOTE]</p><p><br /></p>
