Not his rookie card, but close to it. (Side note - his rookie card is on my short list of dream cards.)
As I spelled out in my post from 2010 (I guess this makes it a double Throw Back Thursday) titled "Six... no, scratch that... Sixteen Degrees of Joe Namath" us Jets fans have been waiting over 45 years for the leadership qualities Namath possessed. Even when the team is really good the QB position just seems to be the position that can't quite bring another Vince Lombardi trophy to the Big Apple. (or New Jersey depending on whom you ask.)
This is card #100 of the 1969 Topps Football Cards release. Simple, clean, & bold.
The pricing on this card can vary widely depending on condition.
If you are trying to purchase it raw (not graded or slabbed) getting it in a condition with issues should run you between $10 and $20, in decent visual condition card in the neighborhood of $25 to $30, and in condition to get you a mid to upper grade about $40 and higher.
Graded versions should start around $20 for lesser grades, about $50 for really nice grades and moving in $70 for NM to Mint and sky rocking to anywhere above $500 for the highest grades.
