You can look through these but most will sell about $100. or less !! Does yours have a name on the bottom ?? They were made by many US mfrs and many were made in Japan !! Keep in mind that what you see in the link are asking prices,,not selling prices The number of cups will add to the price !! Basic set is six or eight cups !!
