Dirty Jobs finally aired the marbles episode on December 8th. It was originally filmed in November 2008 at the JABO factory.
Mike Rowe helped the crew create a very vibrant run of marbles called "Eagles". They are loaded with aventurine and have been for sale on eBay since 2008, though I expect the value will increase now that the show has aired. Right now it looks like you can still grab some for around $5 each.
If you missed this fantastic little bit of marble history, keep an eye out for a repeat on Tuesday, December 15th. Here is a sneak peak from the show:
