If I asked you How much is my 57 Chevy worth, without giving you any description of it's current condition, I don't think you would be able to give me an estimate of any value. It's the same with airguns. It could be a GEM or a DOG. You need to give more information, Give it some sort of rating like It's in, poor, fair, good, very good or excellent condition. Then I have some way of giving you an estimate of value.
You need to state what condition it's in. without more information it is not possible to answer you.
200
Made by who? If you are asking about a Marksman Repeater, then it is not worth much. They only cost around $20 brand new. Used they go for less that $10
About 50 USD
What condition is it in. That determines the value
The Repeater itself is not woth much $10 if it is in great working condition. The Marksman Moving targer may be worth more. I found one on the net for $29. It all depends on who may want to buy it.
It would help if you stated the model and the condition of the pellet gun. Without some information it is not possible to answer you.
Around $50
What model is it. How old is it, what condition is it in, is it still working?
What Condition is it in? That determines the value.
It would help if you stated the condition of the rifle.
What condition is it in. That determines the value.
