The retro market is starting to see sense. The hardcore buyers are no longer willing to pay stupidly inflated prices merely because something is old. Its not totally cured - a lot of sellers who don't follow the market intimately still chance their arm asking top money for old tat because its "retro" or "vintage", but they're achieving these prices less and less. Some semblance of sanity is returning.
Unless its very rare (Clelands) or of genuine historic significance (early Breezers), an old bike is simply and old bicycle, and prices are starting to reconcile themselves to that fact.
