<p>[QUOTE=&quot;Kasia, post: 2961257, member: 31533&quot;]Actually it developed out of Sheldon&#039;s desire to be able to grade a coin (large cents) based on the &#039;value&#039; the coin had compared to one in a Basal state. Basal state was 1 and was a gradable coin (not damaged) that you could read the date on. Each grade above that was supposed to reflect that the coin had a value that many times the basal state 1 graded coin. I guess he could not imagine based on his time, that any coin would be valued higher than 70 times the value of a coin graded in basal state.&nbsp; And he was not trying to grade all coins. The scale was simply adapted to other coins later, and of course, the value of the coins are not directly tied to the basal state in such a neat fashion.[/QUOTE]</p><p><br /></p>
