The model 3100 & 3200 were manufactured between 1958-85. The 3100 is a BB pump rifle.
What condition is it in. That determines the value.
Benjamin made a model 1300 air pistol not a air rifle. It would be worth between $130-$155 in VG shape They were made between 1959-1964 They did make a 3100 air rifle... If you have a 1300 rifle then I do not know the value.....
Which model. Benjamin made about 20 different models. Also state the condition of the rifle.
The 310 series of air rifles were made between 1940 to 1969. Today Crosman air gun co owns the Benjamin line of air products. If you go to the Crosman link below you will find the exact year of your rifle if you can read the Serial number it will began with an "H".
I think it all depends on your definition of "Antique" Is that like really old and worn out? The current condition determines the value. So here is the best guess I can give you. In good condition it is worth around $80-$100 plus or minus. This rifle was made between 1958-1985
My documents only list the overall dates it was made between . 1958 to 1984 see the link below
