Of special note in this marble collection are 70 sulphide figure marbles, many quite rare. An original sulphide marble box set will also be up for sale. Sulphide boxes are exceedingly rare and this one is expected to fetch between $4,000-$6,000.
As I always, I highly recommend you peruse the online catalog and feast your eyes on the excellent photography of these gorgeous marbles and marble box sets.
Update: Here is a video preview of the auction lots.
