<p>[QUOTE=&quot;Conder101, post: 345814, member: 66&quot;]Because of the low density of aluminum, the same weight of metal has 2.64 times as much volume, so you could make 2.64 times as many coins with the same wight of metal.&nbsp; You can make about 180 cents with a pound of zinc $1.16 per pound,&nbsp; metal cost .6 cents per coin), or 479 cents with a pound of aluminum ($1.39 per pound or metal cost of .3 cents per coin).&nbsp; So even at the higher cost per pound, the materail cost per coin is 50% less.&nbsp; Steel weighs about the same as zinc, so in order to get the cost per coin down the cost of the metal has to be less than that of zinc.&nbsp; I don&#039;t know what steel costs.&nbsp; Figure I found for steel plate is around 46 cents per pound.&nbsp; That might give you a figure of .25 cents per coin.[/QUOTE]</p><p><br /></p>
