These all have different patterns

[K.T.]

Do these different patterns signify?

These are all clear gaming marbles, probably foreign 

[Chad G.]

Foreign or industrial, the different wrinkles on them simply signify the cutting shears cut the glob differently.

I have seen a handfull of these that were used as "Polishing Media".
They were made for several reasons but polishing a variety of manufactured items in a tumbler was probably the most used.
Mine were all scar-ed up with a flat or "raspy" finish to them.
Not worth a whole lot of money--just a cool find to me--and an education that came along with them ---which is priceless.
Thanks for sharing these.
Marble--On!!
