<p>[QUOTE=&quot;messydesk, post: 2840864, member: 1765&quot;]This is an <b><font size="7">11 year old thread.</font></b></p><p><b><font size="7"><br /></font></b></p><p><font size="4">The coin posted back in 2006 is copper-nickel clad, as are all other known 1971-D halves except for the one cited above that was graded in 2015.&nbsp; You can easily tell by the color.&nbsp; Uncirculated CuNi has a different color from 40% silver.&nbsp; The weight is pretty close between 40% (11.43 g) and CuNi (11.33 g).&nbsp; You have to have a scale accurate to at least 0.01 grams so that you can be confident in the 0.1 g difference when weighing. The difference in specific gravity is higher. 1971 halves are common and worth face value if circulated, and don&#039;t break into the $10+ range (retail) until they&#039;re graded MS66.</font>[/QUOTE]</p><p><br /></p>
