Paul Tutmarc did not invent the electric bass. Leo Fender did in 1951. It was the Precision bass.
A Fender Precision Bass with the serial number 897396 was likely produced in 1975. Fender's serial number system from that era indicates that this number falls within the range associated with that production year. For precise verification, it's always best to consult official Fender resources or databases.
As to my sources: Your guitar was made at the Fullerton Plant (Fender - Pre CBS Era), USA in the Year(s): 1963
1968 or 1969
1976
The original bass guitar was developed by Paul Tutmarc in the 1930s as a replacement for the double bass, but he received little success for the invention. In the 1950s Leo Fender (who, obviously, is the man who started Fender) took the idea and introduced the first mass-produced bass guitar on the market, the Precision bass. This was hugely popular and since then bass guitars have become the norm in all bands, and variations upon the Precision are still made and extremely popular.
According to the Fender website, your instrument dates from 1973.

Whatever someone is willing to pay for it!
This depends. The Fender Jazz bass has been around for quite some time, so the year could be from the 1960's all the way to now. The best way to find out the year of your Fender Jazz bass is to look at the headstock. On the headstock, you will see a serial number... do a web search for that serial number to find the exact year of the bass.
