<p>[QUOTE=&quot;Oldhoopster, post: 4584715, member: 84179&quot;]Did you search the spreadsheet in post 30 to see if anything matches the weight that was struck in Denver in the early-mid 70s?&nbsp; If something matches then you have a pretty good chance.&nbsp; if it doesnt, then you have to come up with a plausible explanation of how a random unknown planchet got into the Denver minting process.&nbsp; </p><p><br /></p><p>Just based on appearance, however, it looks like the countless plated coins that have been posted here over the years.&nbsp; The 2.8 gm weight is unusual but there is a chance it could be a slightly underweight planchet.&nbsp; Plating adds very little weight and with the 0.1 th resolution on your scale, it might not even register.&nbsp; &nbsp; The variation in weight alone is not enough to prove it was struck on a foreign planchet[/QUOTE]</p><p><br /></p>
