When you ask for the value of this airgun, you need to give me more information than "How much is it worth?" Let me explain. If I asked you "How much is my 56 T-bird worth?" The first thing you might ask is, "What condition is it in?" It could be a real gem or just a bucket of rust. It's the same with any antique. The current condition determines the value.
You need to give a description of the airgun, give it some sort of rating like, it's in (Poor, Fair, Good, Very Good or Excellent) shape. Or tell me that is looks well used or has very little wear. Something that gives me an idea of where to start. Without more information it is not possible to give you an estimate of value.
The Sheridan Silver Streak air rifle with serial number 8691E was manufactured in 1970. Sheridan's production of the Silver Streak models began in the late 1940s and continued into the 1980s, with specific serial numbers indicating their production years.
The 1964 half is 90% silver and has a silver value of $5.89 the 65-69 coins are 40% and have silver values of $2.40 with the price of silver per ounce at $16.29 so many were struck the value is just for the silver. The exception is the 1970-D coin it's 40% silver but was not released for circulation it was only issued in the 1970 uncirculated mint sets and has a value of $10.00
The United States did not produce quarters from silver in 1970, only ones from an alloy of copper and nickel.
Danica Sheridan was born on April 14, 1970,.
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.

This quarter is not made of any silver so a 1970 quarter is only worth 25 centsIt's a common coin, still in circulation, has no silver and is just face value.
Before 1970, half dollars had silver in them, but in 1970, they used no silver in the coins, so it is worth only $0.50.
Michael Sheridan - Irish politician - died in 1970.
Face value only since no silver content.
U.S. pennies have never contained silver. Your coin might be silver plated for jewelry or other decorations.
1965-1970 Kennedy half dollars are 40% silver with a value of about $2.00 for the silver.
The 1970 Washington quarter was NOT struck in silver.
