<p>[QUOTE=&quot;Wal888, post: 8388875, member: 96740&quot;]Hi All of you CT Experts,</p><p>I was sorting by date my US coins collection and saw a 1977 Washington Quarter (among a lot of them I have) wich called&nbsp; my atention. I figured out that coin did weight 5.71 grs. After, I did weight all others I have and all of them weight from 5.54 to 5.63 grs. To confirm precision of my scale, I did weight a 1776-1976 s Silver Washington Quarter (40% Silver Planchet) and the weight is 5.71 grs.</p><p>My question is: Is there possible the existence of a 1977 Washington Quarter (Philadelphia) struck on a 40% Silver Planchet? Or a 1977 (D no D) Washington Quarter (Mint Error)??</p><p>I ask it because there is actually only one or two known pieces of it.</p><p>I took pictures of my coins to show you.</p><p><br /></p><p>My 1977 coin &quot;overweight&quot;</p><p>[ATTACH=full]1488488[/ATTACH] [ATTACH=full]1488489[/ATTACH] [ATTACH=full]1488490[/ATTACH] [ATTACH=full]1488491[/ATTACH] </p><p>Regular circulated coin to verify the scale</p><p>[ATTACH=full]1488494[/ATTACH] </p><p>And a 1776-1976 to confirm the weight of a 40% Silver clad Planchet</p><p>[ATTACH=full]1488499[/ATTACH] </p><p>Any comments are appreciated.[/QUOTE]</p><p><br /></p>
