It would be worth between $65 - $80
what condition is the rifle in.
Sheridan made several C series rifles. I assume that you are asking about the C Silver Streak. Not the C9 Sliver Streak. In order to give you an estimate I need to know the condition of the rifle. Does it still work? Does it hold air. What condition is it in? All these determine the current value.
If it is a "C9 silver Streak" it would be worth around $140. If it is a "C Silver Streak" it would be worth around $235
Around $100 in good condition.
It depends on the condition. You must give it some sort of rating from Poor to Excellent condition in order to get an estimate of value.
Sheridan C silver streak in good condition would be worth between $125 -$160 USD
It all depends on age, use, and condition of the rifle. Is it in Poor, Fair, Good, Very good or Excellent condition. Sheridan made 4 different model C series. The C Silver Streak, C9 Silver Streak, CB9 Blue Streak, and C9BP. Which one are you asking about?
What condition is it in. Without more information it is not possible to give you an estimate of value.
In order to give an estimate of value I need to know the current condition of the rifle.Excellent to poor ( Give it a rating?)
Depending on which version of the Silver Streak, the C Series or the C9 Series the value is about the same. In Very Good condition it is worth around $135 to $155 If it has no wear, scratches, dings, rust, pitting or other damage.
The Sheridan Silver Streak is a 20 cal pump air rifle. To get an estimate of value please state the condition of the air rifle. Is it working? Is it in poor, fair, good, very good, or excellent condition.
I must know the Condition of the rifle to give a more accurate value. But the values fall between $50 in poor condition to $235 in like new condition. Without a scratch on it and no wear.
