It's a C series silver streak from 1972 and there is no real damage except for some small wear on the wood stock. How much is my Benjamin Sheridan .20 cal pellet gun worth?

This is possibly the most frustrating airguns to nail down as to the exact model. First of all let me explain. Sheridan was a standalone company. In 1977 Benjamin purchased Sheridan. Some guns were called Benjamin/Sheridan, in 1992 Crosman purchased Benjamin and Sheridan. They decided to call the .177 and .22 caliber rifles "Benjamin" and the .20 caliber rifle "Sheridan." But for awhile they were called "Benjamin/Sheridan."

So now we have the models C, C9, CB9, C9PB, Along with Blue Streak and Silver Streak. Not to be confused with the Crosman/Benjamin "Super Streak." (Confused enough)

Okay here is what I think your value is according to the Bluebook of airguns 9th edition. in very good condition it is worth between $105 to $135
