Word on the Internet says around 500. I have seen serial numbers that were much more than 500 apart. I have also seen some made in 2009, with mine being made in 2010.
According to several pieces of Fender Documentation, the Year of Manufacture would be 1966. Within a year or so of when CBS took over Fender. (Post CBS)
It would depend on the year the bass was made. For instance, a pre-CBS bass (anything prior to mid-64, when CBS took over from Leo Fender) is worth much more than one made in recent years.
