First of all thank you for posting a question with all the information I need to answer it. Most questions just ask "How much is my air rifle worth." without any additional information.
Your sliver streak, in excellent condition is worth around $190.
A bit of history: Sheridan, Benjamin and Crosman at one time were three different companies. in the 1970's Benjamin bought out Sheridan and continued to market the Sheridan name on the .20 caliber rifles and the Benjamin name on the .177 & .22 caliber rifles. Later Crosman bought out Benjamin and now makes all three lines of air rifles. In 1972 Sheridan started serial numbering their air rifles. Today Crosman has that list. (See the link below)

If the WORKING condition is Excellent. What condition is the pistol itself in. Is it also in Excellent condition or average condition
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.
To determine the value of this air rifle I need to know the current condition that it's in. Is it still working, Is it in Poor, Fair, Good, Very good, or Excellent condition? With more information I can give an estimate of value.
it is in excellent condition
In order to give you an estimate I will need more information about the condition of the Rifle. You need to rate it, something like this. Poor, Fair, Good, Very Good or Excellent. and is it still working. Then I will be able to give you an estimate of value.
In excellent working condition it would be worth between $75-$95. Like New it is worth around $110. W/O scope.
It nice to have someone ask a question with all the information I need to answer it. The AIR-17 in Excellent and working condition is worth around $130. In pristine (Like New) it is worth around $150.
It all depends on the current condition of the rifle. And is it still working. With out more information about the condition it is not possible to answer you. And I think you mean Rifle not Gun.

If it is in excellent working condition about $1500.
There are two CROSMAN Model POWERMASTERS. In Excellent condition they are worth as follows: (This means the rifle is also in Excellent looking condition not just working condition) Model 760 POWERMASTER made in several variations from 1964 to 1991 around $20 to $25 Model 760XL POWERMASTER made from 1978-1980 around $30 to $35. If the rifle is in used looking condition the price drops considerably.
