These are extremely hard to come by and in great shape. My understanding is the Seafoam Green is the rarest of all 4 chips and they will all stand on edge. I haven't seen any offered except for one time and that's when I picked them up years ago. I will take offers starting at $1000 until 11:00 P.M. tomorrow night. I will not break up the set. These chips would make a nice addition to any Las Vegas collection. Please bid them up! Thanks for looking.
