Just out of curiosity, let's do a little "Survey" if you will.
A album on Cogs is listed with the following Statistics:
Lowest: $15.00
Median: $35.00
Highest: $90.00
What do you think the asking price of a VG+/VG+ should be?
For me, the highest is an outlier. Could have been autographed or something.
For me, I would price $35 to $50 range depending on where other listings are at and when the last time it actual sold was.
But last time it sold is key. If it hasn't sold in a long time and there are none currently for sale you have a lot more wiggle room on market value.
