If you are asking how much is it worth? Then in order for me to answer you I need to know what physical condition it is in and is it still working. All this determines the current value.
Rate it something like Poor, Fair, Good, Very good or Excellent. Then I will have something to work with.
Or you can contact "Daisy" directly and ask them. They offer a free service to evaluate the value of older Daisy air rifles and it's free.

See the link below. The information is the same for all Daisy powerline rifles.

Yes.
The current price for the Daisy 880s with scope is about $48
It was made between 1977 to 1989
No it's a spring piston system
I do not recommend it. Its not quite powerful enough
Because it is designed to shoot.
No. Its just a 15 shot BB gun.
No it is not designed to shoot pellets.
NO the Daisy Powerline 1200 is strictly a BB pistol that fires a .175 size BB not a .177 pellet
I suggest you contact Daisy directly and ask for a schematic (see the link below).
