Set of Decorative Spheres in Blue, Gold, and metallic Gray

Set of 8 vintage decorative spheres although not completely round as the bottoms are flat. About the size of a pool ball, 2 gold, 3 varying blues, one pearl and 2 metallic gray. I had these as decor in a clear bowl. One of the gold ones has a drill mark as if someone used it for a gear shift on a car. No clue lol but they are cool and vintage.
