Well, they're almost all modern marbles. Might be one or two which could be id-ed as vintage.
By modern we mean made in 1970 or later.
Many were made since 2000.
Basically it's a nice assortment of marbles made mostly outside the U.S.
The first pic in the gallery looks American. Post-2000 Marble King Rainbos with an acid wash to make them frosty.
As I said a nice assortment follows, including at least a couple I haven't seen before but which I have to assume are modern. It's always cool to see unusual ones from outside the U.S.
The two which stood out to me as good chance of being vintage were #2 and #3 in this photo:
