Hello Diggerbutt!
Nice grab. The marbles shown are from modern to maybe 1980s or so.... so "vintage" may or may not apply. I see a lot of stuff from the 80s being called vintage, so maybe. Some of those cateyes do look like peltier bananas and if so, they would be old for sure. It's hard to tell, are they iridescent? I'm not a cateye expert but I have a hunch they are japanese imports instead. Sorry if it's bad news, but you got some marbles you like, so it's not all bad, right?!
