There are also the Rocky Mountain 93 Altitude team bikes on here, both a USA and a UK one.
I have an 1991 version that belong to our UK lot.
Certainly can't really see any extra value in them, the 93 may have as it has a different paint job to the retail bike. Still cheap though.
There have been prototypes etc pop up and the Formula1, PACE, Lotus, Raleigh UK, Orange bikes etc
Most have been 'for the love of doing it' on here and I think most probably cost the owner more than it's saleable value.
If you're thinking money, you may try some of the vintage retro alumni groups.
Insurance doesn't care, at least mine didn't, but they did pay a fair replacement cost.
