I just put up 10 listings on eBay for marbles that I'm selling. My eBay user/seller ID is assortedoddments. Active link to all my marble listings can be found here.

What you'll find are several lots of Vitros, including two special hand-picked lots of some really very spectacularly nice marbles. There is also a nice lot with some big Vitro shooters in good condition and some other stuff. All listed as auctions, low opening bid, no reserve. I have some other stuff listed too, but the above link just shows the listings that are for marbles.

Thanks for taking a look.
