The price will be whatever someone is willing to pay for it. The reason the catalogue has no price is that there is no data.
FWIW: My experience in selling re-entries/varieties on
ebay tells me the real-world value for your nice used copy would be in the $20 to $30 range.
You might get more on a large auction site - but the fees would probably make it around the same as far as "take-home" $.
