In reply to atrendall:
The axes are collectables and/or wall decorations.
Use the well known internet auction site. Chouinard axes (inc those stamped Interalp Camp) go for a tidy sum; think £75 -£150, I know as I have recently sold one (laminated bamboo shaft. If the shaft is obviously laminated (and it sounds like it is) then it is most probably bamboo which will attract a bit more of a premium.
If the Stubai axes are stamped Aschenbrenner then they will have a modest value although I have seen them go for up to £40 (or even more but I wouldn't raise your hopes too much).
Happy selling
