35 years ago when I started to do gun shows, the average Mod 12 went for $300. They are less than that now. The average Mod 97 now runs $350-450 depending upon what part of the country you are in. Custom Mod 12's are more but custom 97's (factory engraved 97's) are very rare and very expensive. Lil John had an engraved 97 cased with two sets of barrels which went for a lot of bucks (but I don't know how much). 97's are now more expensive than Mod 12's.
