There is no definitive answer. Vintage values fluctuate from day to day.
Best bet... get an idea from Kelly Blue Book or Gruhns guide... then watch Ebay completed listings for a while (watch the SOLD listings, not just the expired ones... just because someone puts a Supro Ozark up at $2500 doesn't mean thats what its worth)... use your best judgment between the two resources to make your own determination.
