<p>[QUOTE=&quot;Conder101, post: 831374, member: 66&quot;]Actually it&#039;s a bit problimatic because believe it or not aluminum is actually very hard on dies and tends to wear them out fairly quickly.&nbsp; The problem is that bare aluminum is very reactive and almost immediately develops a coating of aluminum oxide.&nbsp; This coating then protects the metal from further oxidation.&nbsp; he problem comes when you strike the planchet and the metal expands outward dragging that oxide coating with it over the surface of the die.&nbsp; Another name for aluminum oxide is carborundum which had a hardness rating of 9, just below that of diamond.&nbsp; It is the same abrasive found on the best sandpapers.&nbsp; One way o avoid the problem would possibly be to continue coper plating the blanks.&nbsp; The copper would protect the dies from the oxide coating.</p><p><br /></p><p><br /></p><p>Gold?&nbsp; No.&nbsp; But it was on a par with silver, a little over a dollar an oz at the time.</p><p><br /></p><p>The Louisiana Tax tokens were made of aluminum and I believe several other states hade aluminun tokens as well.[/QUOTE]</p><p><br /></p>
