The overall composition of the new Golden Dollar is 88.5% copper, 6.0% zinc, 3.5 % manganese, and 2.0% nickel. The coin&#039;s composite construction provides security features that allow machines to distinguish it from slugs, tokens, and foreign coins.</p><p><br /></p><p>Read more: Sacajawea Golden Dollar <a href="http://www.infoplease.com/spot/sacagawea1.html#ixzz1OT85nxpE" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.infoplease.com/spot/sacagawea1.html#ixzz1OT85nxpE" rel="nofollow">http://www.infoplease.com/spot/sacagawea1.html#ixzz1OT85nxpE</a></p><p><br /></p><p><br /></p><p>Maybe it is struck on a 1999 SBA planchet ?&nbsp; I&#039;m not too familiar with these useless modern coins....[/QUOTE]</p><p><br /></p>
