Hi Serine. Welcome.
I think mostly a fun collection.
Mixed ages.
Some from around 1930 and a smattering of others right up to modern day. Also a mix of makers. Peltier, Vitro, Master, Peltier, some from Asia (we wouldn't be able to tell company names for those), and I think some from West Virginia swirl companiees.
In your last photo, there is a black and red one which might be the most valuable in the lot -- assuming it is mint condition -- which I'll guess it isn't. A single chip can knock marble value down by half or more.
One very interesting one to me is the swirly one with the inky blue ribbon on a white and clear base, with a touch of yellow.
Nothing is standing out as very valuable, but I'd pull out the two I mentioned.
