How do you properly value a mid-grade item not on the Sheet?

I've heard conflicting ideas about this. Say you have a coin that is an AU55 and the Sheet says $100 in AU50 and $160 in MS60.

One dealer I know would value the coin at $130 (which I have actually bought into on a couple coins of his priced according to this method). Other dealers price it more "logarithmically" where AU58 might get $130 price, but AU55 would get maybe a $120 and AU53 would be $110.

How do you value/price mid-grade coins?

Personally, I think it makes sense to price it closer to the lower grade.

The math geek in me would plot the prices that are listed, fit a curve to them, and then use that curve to determine the appropriate value.

The lazy ass in me would probably just make a WAG.

For Canadian coins, If the coins is worth $50 in G4 and $120 in VG8.
The price for G6 will be (120-50)/2 + 50=$85

I think it works the same in US coins.
Hope that helps.

I voted #3 because I think it is more complicated and cannot be generalized.

If it is a ho-hum fairly common coin, I would value the mid-grade closer to the lower grade. If it is a coin of moderate scarcity (absolute or conditionally), I might value the coin at the mid-point. If it is a coin that has a population of 50 in XF-40, 1 in XF-45, and 1 in AU-50, I would value the coin in XF-45 closer to the AU-50, to use an extreme example.

I always go by "gut feeling" on these in-between coins, and there is no formula you can use. Each coin is different and has to be considered for its own merits and eye appeal. For example, I recently paid MS-60 money for several really nice AU-58 type coins. On other occasions, I've seen certified AU55 coins (NGC mostly, sorry) that I wouldn't pay XF-45 money for. So it is basically a matter of eye appeal. Look at the coin and ask yourself "is that a $100 coin or a $160 coin?" More often than not, your instincts will tell you what you ought to pay.
