<p>[QUOTE=&quot;tj carr, post: 2399902, member: 78148&quot;]metal detectors don&#039;t lie...they could give you a baseline. if its copper it will sing like a banshee. according to the mint press release dated 12 7 73 they tested 7 different alloys. the questions are how many different planchetts were made&nbsp; and what happened to them? how many were clads,sandwitched, plated. if it looks odd it is. reports of a steel zinc, pale yellow,grey, even odd ball red have been discussed. bee advised that coin weight of 94 is aluminum, 3.11 could be other different&nbsp; alloys. the pennies found in circulation are fair game. the us mint released them during the course of business as usual as currency of the realm for the usual purpose to be circulating currency. tj carr[/QUOTE]</p><p><br /></p>
