Someone who has sold that many marbles should know that that 1/8 of an inch makes a huge difference to marble collectors.
4/8 = peewee
5/8 = average marble size
6/8 = shooter
This is crucial information. GP is not incorrect here.
Love 'em all but the Vitros in the Red Horse bag made my heart speed up. Now that I look closer I see the Vitros in a couple others. You are so strong to be able to collect bags and keep them all intact.
Interesting pattern on the Marble King bag (Victory Foods). Not sure if I've seen that one before.
In my opinion it would not be an old car.
I just watched Babylon 5 for the first time about a month ago. It was set in the year 2258. In one episode a guy claimed to have a mint condition Kawasaki Ninja motorcycle. It was actually assembled from parts he found here and there so I scoffed at him calling it mint condition. My opinion then and now is that if it wasn't an original build from when it was originally made. then it's something else. May still be super cool like that motorcycle would have been. But it wasn't an old motorcycle and it wasn't mint.
To me it doesn't look like it's veneered all over. Looks like a green band on a black/brown base, which I don't recognize as a Vitro variation. And with it being in Holland I can't help thinking it could be a foreign marble.
