<p>[QUOTE=&quot;physics-fan3.14, post: 2104180, member: 19165&quot;]The idea of split grades (separate grades for obverse and reverse) has been tried by companies in the past. The old ANACS photocertificates are known for this. I am a fan of the idea myself, but the market chose to go with a singe grade. The problem with split grades is that they are too hard to price - What is the difference in price between a 64/65, a 65/65, and a 65/64? </p><p><br /></p><p>Is the 64/65 the same price as the 65/64? The answer is no - because the obverse is considered more important. It is widely acknowledged that in market grading the obverse carries more weight (I&#039;m not entirely sure why - but it does). A strong 65 can pull a 64 reverse up to a 65, whereas the opposite is not true. A 64 obverse with a 65 reverse will usually be graded 64. If I had to weight the importance of the sides, I&#039;d probably go 60/40 in favor of the obverse (according to the TPGs). Again, I&#039;m not saying I agree with this, I&#039;m saying that&#039;s how it is. </p><p><br /></p><p>The same is true for toning. A coin with stellar obverse toning is going to sell for much more than a coin with the exact same toning on the reverse.[/QUOTE]</p><p><br /></p>
