This lot of 30 vintage marbles features striking uranium streaks, with swirls, cats eyes and unique marks, measureabout 1/2” in diameter. They were in my grandfathers collection believed to have been acquired in the 50’s and manufactured in the United States. While the artist and type are unknown, the marbles are sure to add a touch of mystery and nostalgia to any collection. Perfect for collectors as a fun addition. These marbles are a rare find for anyone who appreciates vintage toys and games.
