I don't believe Coleman ever made a pellet gun or rifle. However Crosman did make a model 2200 from 1983 to 1988. If this it what you are asking about then please state the current condition of the rifle, not gun. It is not possible to give an estimate of value without more information like is it working? Is it in poor, fair, good, very good or excellent condition?

50-150 USD
What condition is it in. That determines the value
It would help if you gave the manufactures name and the current condition of the pellet gun. without more details it is not possible to give an estimate of value.
It depends on the model and the caliber of the Pellet gun.
$1800-$2200 mint condition, this gun is rare
Please state the condition of the pistol to get an estimate of value.
What Condition is it in? That determines the value.
I think you mean pellet gun. That is a gun that fires a small lead pellet but does not use gun powder. It uses compressed air or compressed gasses to push the pellet.
A pellet gun is not adequate for protection, and will get you arrested.
It all depends on the model and who made the pellet gun. I suggest that you re-post the queston with the model and make of the pellet gun to get an answer.
