Hard to say, but I personally wouldn't bet on it. The difference between the new Jabos and antique marbles being that the new Jabos were made then instantly put into collections. Antique marbles were not. They were played with, lost, thrown away...etc. Basically, in my opinion, Jabos were made by collectors for collectors and there are plenty to go around. Some of the exceptionally nice examples my fetch premiums later on. I have many of the different runs myself, but I did not buy them as an investment.
