<p>[QUOTE=&quot;dcarr, post: 2765853, member: 4781&quot;]I was striking some coins today and performed a test.</p><p>With the planchet sitting in the coining chamber, I put a small drop of water on the planchet. The drop was located were there was a recess in the die above it. The recess was a facial portrait. I expected that this recess would trap the water when struck. The result was that the entire coin was fully struck except where the water was trapped. The facial portrait details were missing and there was a smooth shallow depression on the struck coin where the face was supposed to be. This was as I had expected. Water is incompressible, and if it has nowhere to escape, it will make in impression in the planchet. If the drop was near the edge and not in the center, it might squirt out at high velocity before interrupting the striking.[/QUOTE]</p><p><br /></p>
