at this point I hesitate to try to answer that but it certainly seems possible.would love to know the answers to this mystery for sure.always hopeful more info will come to light.I have gotten about 1600 all from the same source recovered half buried from decomposed box(s) around an old barn in the country.original source is deceased so the how and why of how such a large stash (all older asian imperials -very curious to me that there were no other kinds of marbles)came to be there is probably unknowable.good times
