What is the age and value of a 22 caliber Remington Model 12?

They weren't date coded until 1922, date can be determined serial no.

The manufacture dates for this model are between 1909 and 1936. Go to the Remington web page and type in the date code where prompted. The date code is 2 or 3 letters on the left side of the barrel. However I do not know the value of these gun. I am looking for that answer myself.
