Depends on condition and completeness. The rifle had 3 sights- front, rear barrel, rear receiver, and Mossberg quick detach sling swivels. If sights or swivels are missing, they are expensive to replace. Well worn specimen $100, excellent complete specimen $250-$300. Active collector interest in Mossberg 22s from this period. (Nice rifles- have 2 of them)
35-100 USD
I believe the gun is worth about $200. in excellent condition.
