I bought some chips today from an estate. The chips are red and blue and have the initials "NYC" hotstamped on each side.They have small rectangle mold around the chip.

Also there were two other chips pink($1.00) and black($5.00) with the initials "LBK" on one side and the denomination on the other (the "L" of "LBK" is kinda squiggly looking)They also have a "chain" design mold that runs around the chip. Does anyone know the origin of these chips? Any information would be much appreciated. If you email me, I can send you some photos of them.
Thank you,
Jim Davis
