<p>[QUOTE=&quot;Conder101, post: 1733408, member: 66&quot;]A 1965 half on a coppernickel clad planchet would be impossible unless the half dollar planchets were punched from quarter thickness CuNi clad strip.&nbsp; (There was no CuNi clad strip of half dollar thickness at the mint until 1971.)&nbsp; And a half dollar struck on quarter clad stock would weigh 9.01 grams.&nbsp; Your coin is much too heavy to be that.&nbsp; It is NOT possible to tell a 40% silver clad half and a coppernickel clad half apart by weight.&nbsp; Due to the tolerance range allowed by the mint the 40% silver half can weigh anywhere from 11.9 grams to 11.1 grams.&nbsp; A copper nickel clad half can weigh anywhere from 11.89 grams to 10.89 grams.&nbsp; So unless your coin weighs between 11.09 and 10.89 grams you can&#039;t be sure it is copper nickel clad.&nbsp; Your coin falls well within the size and weigh range to be a normal 40% silver half dollar.</p><p><br /></p><p>If you reaaly want to check and see if it is 40% silver or Copper nickel clad do a specific gravity test on the coin.&nbsp; A 40% silver will have a SG of 9.53 and copper nickel is 8.92[/QUOTE]</p><p><br /></p>
