Sandy,

I dont know if this is posible, but anyway here goes...

Could the info concerning the price of each puzzle be calculated in our own collection ?

Michael

I could try. I'd have to use either the mean or median value of each puzzle's current price, which may not be the most accurate system. Also, there are about 1000 items in the database that have no price information at all. What would the formula do for those? Insert a standard low value (say $5) for each?

Sandy

That would mean, for example the Windmill Cube by Katsuhiko Okamoto would be considered $5 worth.
I think its better, to ignore puzzles without price and mention the number of puzzles on which the calculation was performed.
