I don't know their age. They were on eBay, labeled Peking glass (and purchased today not by me); but in my opinion (and that can be taken with a grain of salt because I'm not knowledgeable about beads) they appear different than the fabulous early melon Peking glass beads that were / are still pictured in the gallery section of the forum.

Needless to say, I love melon beads too.
