1940s, maybe a wee bit later. I have seen them on the net, very cool find.

Looks like a PPP (Peltier Peerless Patch), probably early/mid 30s to mid 40s. Good Job Tom! Lots of marbles are UV reactive. Some will surprise you!

Besides the green ones, I have some that radiate orange also. I used to collect vaseline glass as well.
