At one time Sheridan, Benjamin and Crosman were all separate companies. In the 1970's. Benjamin bought out Sheridan and took over the company. In the 1990's Crosman bought out Benjamin. Now Crosman owns all 3 companies. When Benjamin bought out Sheridan they decided to keep the C series design. So they decided to keep the Sheridan name on the .20 mm air rifle and put the Benjamin name on the .177 and .22 caliber 392 series air rifle that looks just like a Sheridan C Series. So All Sheridan C series are .20 caliber and the .177 and .22 are Benjamin's. Crosman decided that this worked well and kept the same arrangement for both models.
If you go to the Crosman home page you will find (At the bottom of the page) a link to (Owners and Parts Manuals) there you will find the owners manual in the Benjamin / Sheridan section.
Your rifle can be aged based on its serial number. Please see the link below.
Sometime around 1980. In 1977 Benjamin bought out Sheridan and for a time they merged the names Benjamin/Sheridan.
The Benjamin Sheridan C9A was made between 1993 and 1998. the company is owned by Crosman. From 1998 to 2000 the 20 cal was named Sheridan and the .177 & .22 cal were called Benjamin. Originally Benjamin, Sheridan and Crosman were 3 different companies. Crosman now owns all 3. At one point The Benjamin was called a "Benjamin Franklin" as a marketing ploy. Trying to follow these name can really get confusing at times.
It depends on the model, but usually it is right on the barrel or the receiver. If it is really old it may not have a serial number. For a time Benjamin and Sheridan did not serialise their rifles.

No. a 177 is a 4.5mm pellet. A 5mm is a 20 cal pellet. A 5.5mm is a 22 cal pellet Don't try it in the wrong airgun.
I believe you are asking about a Sheridan .20 cal (5mm) air rifle. They started to make this rifle in 1949 and stopped in 1990 ( sheridan sliverstreak model ) During the 1990's the name changed to C9 sliverstreak and C9 bluestreak. The value is determined by the current condition of the rifle. You did not give any such information , therefor I can not answer you.
In order to give you an estimate of value, I need to know the current physical condition of the rifle. YOU need to give it some sort of rating like "Poor, Fair, Good, Very Good or Excellent condition." Without some rating it is not possible to answer you. Today Both Benjamin and Sheridan are owned by Crosman Air gun company.
