This auction contains some of the rarest handmade marbles you're likely to see up for auction any time soon. Bids have already reached US$10,600 with just one day remaining, but the reserve price has not yet been met.
Among other gems is a nice big "lightning strike" marble, which is an extremely rare type of banded opaque swirl. I really like the look of that 1 1/2" naked base clown Josephs/onionskin too.
There are several close-up photos of the marbles so be sure to check it out.
Update: Final bid on this lot was $13,000!
