Vendor claimed the chips came from a club at 280 Madison Ave, NYC. Said his father worked there in the 50s. TGT has a listing for CP with SQSQDI as unknown. Anyone have any more info? Anyone have access to old NYC phone books / records that may shed light on this chip? He had approximatley 400 chips which he offered to sell for $550.00. I passed. Other side of chips in next post.
