That's right about when I got my first pair ! I was born in 1959 so I'm assuming you're close to my age.
IMO, the "fifties" ended when The Beatles arrived, and the "sixties" ended when Nixon resigned.
The "seventies" pretty much ended when they were supposed to.
LOL...
I was born in February of 61, so it looks like you, me, and Klar are some of the few here that remember the Silver/Bronze transition as it happened.
