I can tell you have high hopes for them, but unfortunately they aren't rare valuable handmade marbles. They appear to be marbles made for glass transport. Glass has to be shipped somehow, and often it is made into crude balls to be loaded onto rail cars for shipment, then remelted into whatever the next use is... often fiberglass. The color can vary but blue-green is the most common and trash, wrinkles, bubbles, and strands of other colors and contaminates is common in them. It's just industrial grade glass. It can be fluorescent or not, it's just whatever scrap glass got melted down for stock. They are rough and have these characteristics because they are mass produced on machines with little to no quality control or concern about bubbles, wrinkles, colors, or anything at all really. Not collectible really other than as a novelty.
