I think they'd start appreciating according to their current desirability.
As others noted, the value of 27s, 29s and other highly-coveted models would likely rise first. It'd take a good while for "lesser" models to spike in value, and even then, they'd continue to take a relative back seat relative to those mentioned.
And by the time they reach current Python values, inflation will have insured you wouldn't experience the same sticker shock.
