Wasn't sure how to title this question , so here's the gist of it : a certified coin trends for $200 in VF 20 and $500 in EF 40 and $1000 in AU50. What should the VF30 and EF45 prices be , in the mid range or closer to the higher grade ? Thanks in advance.

If you have a value for the various grades for a particular coin, plot those values on a graph, the mark your coin on that graph, between the grades.
In reality, you only need to know the value for the grades immediately above and below your own, and your coin should sit between those grades.
After a while you get good at it. I do it by interpolation between the grades mentally, and how close to the known points your coin is. Knowing that the value graphs are exponential in nature helps.

As a rule of thumb VF30 is about 1/3 of the way betwee VF20 and EF40,if VF20 is $200 and EF40 is $500 then VF30 would be about $300.Similarly if EF40 is $500 and AU50 is $1000,EF45 would be about $665.

DBM: You got it!  That is the mental system I use. Gives the easiest approximation to the exponential curve.

do not agree.. a 30 is exactly between the 40 and the 20.....50/50 or how about AU58? Value: 50+60:2= 55 +60:2 = 58+- i believe that is how most dealers look at it...

I think DBM and sel ar correct...pricing tends to follow an exponential curve not a straight line as coingirl suggests....

I am with DBM and sel on this, but agree that it is subjective to the dealer you are talking to.

Interesting thread! Here's my perspective: inbetween grades exist to fit those coins that are so darn close to the higher grade the differences are arguable but negligible. The inbetween grades exist to catch and coddle sliders. For instance, a VF-30 is far far closer to an EF-40 than it is to a VF-20. Pity that such associations have little effect on pricing. What I've found holds true is that usually an inbetween grade will garner 25% of the spread between two standard grades. I don't like it because I often sell but I have to accept it.

If you want to do it accurately sel's advice with the graph is the best way to go. Otherwise I agree with the mental calculations of DBM and sel. As sel points out the relationship between grade and price is usually exponential so if the grade is in between it will not be a 50/50 split in price.
