Raphaël,
Age does not matter much with Hasselblad equipment. As long as it has been looked after properly, and was not 'beaten to death', a 1979 camera is perfectly fine.
The CB Planar is of a simpler, (a bit) less expensive, and indeed a tiny bit lesser quality, optical design.
Consequently, it is considered a bit less desirable than the other 80 mm lenses too. And that should be reflected in the price. It certainly is something you can use to try and get the price down a bit.
A similar things applies to Hasselblad film magazines: the inserts and shells are matched, and a matched pair can be recognized by the number on the insert being the same as the last three digits of the serial number on the shell.
Being an unmatched pair does not influence the quality of the result by an appreciable amount, yet unmatched pairs are considered less desirable, and should be cheaper than matched pairs of similar age and condition.
