Can anyone tell me about when my cav uss12-96 was made by the picture in my avaitor?

I want to say 1981 but cant be for sure. That was the last of the cav squaretop 64's

I will check that come Monday.  I have it in a break room at work.  Best I remember the only tags above the coin mech have to do with the coin mech and they are silver.  I actually have a metal data plate rivided on the side outside of the box.  It has the model Number and serial number along Cavaliers name as the manufacture.  Funny thing the serial number is 270482, like 27th day 4th month 1982?  Guess I am just reading something into nothing there.
