Lot of 3 Machine Made Larger Size 7/8-1 Inch Shooter Marbles Multicolor Swirls

Lot of three machine made glass marbles, larger shooter size. Approximated sizes, left to right, 7/8, 15/16, and 1 inch - measuring simply using a ruler, so estimated sizes. Opaque colors on all. The first has swirls/bands of white, a rusty red, purple, tan, green, blue. The second has aqua swirls/bands on a gray base. The third has various shades of yellows and blues. Unknown manufacturer/age, though pre-2000. Played with conditions, so some sparkles, but no major chips or cracks.
