<p>[QUOTE=&quot;lightrain, post: 1266620, member: 33057&quot;]repunched mint mark</p><p>That&#039;s a nice combo of errors. I offer an equation of probabilities for review... I &#039;ll call it the <b>cococo</b> ratio- <b>co</b>mmon error <b>co</b>mbination in <b>co</b>mmon grade. Price of one error ($8 for RPM) multiplied by price of next error(Around $5 for BIE?) multiplied by grade/70 (in this case 45/70). That gives $25.71. If it was a vf-20 it would equal $11.43, if ms 60 then $34.29. Of course this equation will fall apart at the extremes, i.e. a MS-70 for $40 would be unrealistic. </p><p>The equation would require well established prices, which would be available on the somewhat common errors. Of course this may be just drivel, but I figure it would be an honest, probability based equation used as a starting point in negotiations. What say you?[/QUOTE]</p><p><br /></p>
