<p>[QUOTE=&quot;SuperDave, post: 2422822, member: 1892&quot;]<b>I&#039;m</b> not sure of it any longer, after hearing the alloy composition.

I overlaid a known 4A onto your reverse and it was exact, but the obverse image, having been shot at an angle, is distorted and spatial relationships won&#039;t line up correctly.

Just not necessarily for the reasons he thought. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
