The venerable Remington 1100 is a semi-auto gun. Well used, they tend to fetch $350 around here. Pristine examples with vent rib and choke tubes are priced closer to $500.
The Remington 870 is a pump gun that looks similar. The two common varieties are Express: $200-$250 depending on condition and Wingmaster: $250-$400. Of course, higher grades of both guns were offered.
