<p>[QUOTE=&quot;rick, post: 76274, member: 1235&quot;]I probably should have just bumped the old topic, since I know there are already a few - OldDan will just have to sue me.</p><p>&nbsp;</p><p>OK, so I was reading Travers&#039; book, and he mentions that the Sheldon scale is base on the following formula:</p><p>&nbsp;</p><p>Book Value = Basal Value x Numeric Grade</p><p>&nbsp;</p><p>in his example, $80 (book value) = $2 (base value) x 40 (numerical grade)</p><p>&nbsp;</p><p>So, heres where I run into a logic issue with market value&#039;s pushing up the grading standards (or pushing them into the ground, depending how you look at it).&nbsp; The market ALREADY has its say in the basal value of a particular coin - if demand for a coin pushs the market value up, it is reflective in the equation within that value.</p><p>&nbsp;</p><p>In this respect, it only stands to reason that numeric grade needs to be static - or at least should be, sans subjectivity without dishonesty.&nbsp; The book value of the coin can still slide based on the variable set up to allow for market adjustment.</p><p>&nbsp;</p><p>So perhaps the standard was poorly explained, or more likely poorly understood on my part, because I am not seeing the grade as dependent upon the market value - I see the book value (of course) being a computation set up determined upon the state of the coin and the base multiplier of value, which appears as a round-about rule of thumb for the age old determination that price is determined between supply and demand.&nbsp; Granted, I think it has flaws, because as the number approaches the ever mythical value of 70, I think the formula is more geometric than algebraic (which I probably would have sounded smarter if I took the time to look that up and make sure I spelled it correctly) - but whatever works to how you determine what you feel is a fair price for a certain coin in a certain grade is fine with me...</p><p>&nbsp;</p><p>I am still, after ALL this time, failing to see reason, except in terms that the market will adjust on whatever terms the market will accept.&nbsp; I guess that&#039;s the only valid argument I can see - because it is market proven.&nbsp; In other words, it&#039;s up to those who comprise the market to reject this foolish notion of shifting grades to accomidate market price.</p><p>&nbsp;</p><p>Has anyone seen any impact in the market trends that resulted from this recent &#039;adjustment&#039;?[/QUOTE]</p><p><br /></p>
