<p>[QUOTE="GDJMSP, post: 452159, member: 112"]Part of what you say is true, but not all of it. Yes, they based the weight of coins on so many coins per marc. But they knew exactly how many coins of a given denomination they could get out of that marc. And they were quite careful, even more careful than we are in today's world about the weight of each individual coin. And they weighed them to within a hundreth of a gram.</p><p><br /></p><p>The reason the hammer struck coins are often not round is a direct result of that careful weighing. For after they would make a planchet, each and every planchet was carefully weighed. If it was light, it was tossed back into the melting pot. But if it was heavy, depending on how heavy it was, small pieces were cut off the edges or it was metal was filed off until the planchet was the exact weight they wanted.

So the vast majority of the time the planchet makers made the planchets heavy. For it was much easier and cheaper to clip small pieces off the edges until the desired weight was achieved.
