(most of) three OLD sets of dice in a plastic box

Three different 'sets of three' dice here, in a small plastic box. They all appear to be made of "antique" plastics. I'll also offer my guesses to which kinds of plastics they might be, but those are only GUESSES based on what I might (or not) have learned about such things, mostly from here. PLEASE correct me if I'm obviously wrong?!! :-) :-) :-)

Set 1 is orange colored with black dots. There is some graining in the orange, I will guess they are bakelite.

Set 2 has white dots with a deep translucent green color, with yellow/gold speckled marbling inside near the edges. I'll guess they are some form of lucite, because I'm not aware of bakelite being so translucent.

Set 3 were *probably* a clear to yellow color, maybe also translucent, and maybe even a 'pair' and a 'single' that didn't quite match. Two of the three have shrunk and at least cracked/fractured while the third has shrunk even more and actually began to go to pieces on its own while in the box, it now has a noticeably different appearance and all three are in fact *stuck together*, while the other six remain loose. (and presumably 'usable')

The plastic box itself is also kinda interesting, it does not have any visible means of its halves being held together by anything except now-dried-out tape, and it is molded of a much thicker than now typical clear plastic with all rounded interior corners. No marks on it.
