Wondering about authenticity of this piece (possibly 1807/6?). Or contemporary counterfeit status?

<p>[QUOTE="Rhazada, post: 4295968, member: 111630"]That is certainly within reason, however I might be slightly skeptical of a coin like this retaining so much weight unless it was closer to AU or so condition, this coin is pushing perhaps an F grade or lower? I will have to look into weight tolerances of coins in general to get a better idea. Another thing to consider which occurred to me shortly ago is that mass could also have been lost due to the coin having been cleaned at some point, perhaps even scrubbed. Some methods of cleaning will remove the topmost layer of the coin, which is why it is so often discouraged unless the outcome is worth the risk. A more vigorous cleaning or polishing would also flatten misshapen high points. </p><p><br /></p><p>So while I will say I am skeptical of a coin staying within weight tolerance at medium to lower grades (it may have even been closer to the low end of the tolerance at its creation), you are absolutely right about calibrating my scale properly, and I’ll look into doing that as soon as I can. My original calibration weight went missing and that has been a nuisance <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie7" alt=":p" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
