<p>[QUOTE=&quot;mrshmooze, post: 1582658, member: 38868&quot;]In a previous thread (here is reference I asked for help identifying a blank planchet.&nbsp; It had the dimensions of a quarter (thickness and diameter) but the weight was 6.55 grams.&nbsp; In other words, initially I thought there is no way that it is a blank quarter planchet.&nbsp; I originally thought maybe it was a blank planchet to a foreign coin, and posted my ? on this site hoping for the vast knowledge you all have on errors and coins in general.&nbsp; </p><p><br /></p><p>Tonight, I found a link at error-ref.com where State Quarters were struck on an experimental alloys, and weighed around 6.5 grams.&nbsp; </p><p><br /></p><p>Please read below</p><p>____________________________</p><p><br /></p><p style="text-align: left"><b>Experimental Issues:</b></p> <p style="text-align: left"><b>Statehood Quarters Struck on Experimental Alloys:</b></p> <p style="text-align: left"><b>Definition: </b>In the years 1999 and 2000, some statehood Washington quarters were struck on planchets composed of a number of different alloys.&nbsp; These alloys were candidates for use in the striking of Sacagawea dollars.</p> <p style="text-align: left"><br /></p> <p style="text-align: left"><br /></p><p>[TABLE=&quot;width: 100%, align: center&quot;]</p><p>[TR]</p><p>[TD=&quot;align: center&quot;]<p style="text-align: left">According to Heritage Auctions, &quot;The U.S. Mint conducted metallurgical tests on various alloys in its effort to select a suitable composition for the Sacagawea dollar. Presumably, quarter-size planchets and dies were more convenient to use than their small dollar equivalents. A small number quarters struck on experimental planchets are known for each of the five states struck in 1999: Delaware, Georgia, Pennsylvania, Connecticut and New Jersey. These dies would have been available by early 1999 for the production of proof sets. Some of the experimental planchet pieces were analyzed with energy-dispersive x-ray spectroscopy to determine their composition. The predominant metal was copper, followed by zinc, with traces of manganese and nickel present.&quot; <span style="color: #000000"><font face="Book Antiqua">The 2000-P Massachusetts statehood quarter was struck on a planchet that weighs 6.48 grams.&nbsp; Its composition has never been established.&quot;</font></span></p><p>[/TD]</p><p>[/TR]</p><p>[/TABLE]</p><p><br /></p><p>Here is the link to this article.&nbsp; <a href="http://error-ref.com/State_Quarters_on_an_Experimental_Alloy.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://error-ref.com/State_Quarters_on_an_Experimental_Alloy.html" rel="nofollow">http://error-ref.com/State_Quarters_on_an_Experimental_Alloy.html</a></p><p><br /></p><p>[TABLE=&quot;width: 100%, align: center&quot;]</p><p>[TR]</p><p>[/TR]</p><p>[/TABLE]</p><p><br /></p><p>__________________________________________</p><p><br /></p><p>That said here is the apparent blank quarter planchet (unconfirmed) </p><p><br /></p><p><br /></p><p>[ATTACH]219055.vB[/ATTACH][ATTACH]219056.vB[/ATTACH]</p><p><br /></p><p><br /></p><p>Anyway, long and short of it, would it be a stretch to say that this planchet is then a blank experimental alloy quarter planchet, or am I reaching taking deductive reasoning into the world of imagination/delusion?&nbsp; Your thoughts please.&nbsp; I really want to see what you all think on this.</p><p><br /></p><p>Thanks</p><p>Tyler[/QUOTE]</p><p><br /></p>
