If the PCGS price guide only lists prices for MS60, MS63 and MS65...

is there a way to find a value for a MS64 on their website? I know you can usually get the value on Heritage's site if you can find a coin that sold in their database.
Thanks.
Thanks.

Please elaborate on the function.

<< <i>I always thought it was a logorithmic function (base10) such that the value was about 1/3 of the way between the grades. I understand the previous formula, but I don't understand how it can be used to calculate the approximate value between two listed grades.

I'm really not sure, but I saw this on episode of Family Guy and they said it could be applied to any situation.
I think they are still working on a format, that will give us( Heritage already has it available) access.
In the meantime, just keep searching.
This actually works quite well, I do it in my head at coin shows all the time

Then compare the expected prices (ie the price guide price) to the actual prices and see how many standard deviations they're off.
That would be a neat thing to do if someone had the time. I might even give it a shot for 1921 Peace Dollars.
