Nice Pelts Chad all the larger size ones I've ever found have been beat into submission except the one I have. The large ones are definitely not an easily acquired item.
Wasn't a "Winnie" one of the Veiligglas marbles from Amsterdam named after @winnie ??

These are all Vacor De Mexico (Mega) IMO, all very common, please try and limit the amount of marbles for ID to 1-3 marbles so no one gets lost. a measurement of each would help tremendously in certain ID circumstances. Oop!! looks like Ric did it the short smart way and I took the long road home ID wise
I suspect Vacor but some very similar are manufactured in China
Newer Marble King
All Peltier MCS ( Multi Color Swirls )except the last maybe 2 I'd consider just a Rainbo's. 3 to 4 w/ multiple views of each is a good max to stick to when posting for I.D. purposes so no one gets confused. The seams if any are present are key to a proper I.D. ( basically 4 views or each side of the marble showing all aspects is best) also a good measurement in fractions if possible.
