You know that Discovery Channel show called Cash Cab where you get into a cab and it turns into Who Wants To Get Paid for Answering Some Questions During the Ride? Well, this is kind of like that, with no cab. And no questions. But you basically get paid for showing up -this time with unwanted, mismatched or “bad-memories” gold, platinum or silver pieces that happen to be hanging around your house. Come to the Hyatt Regency-Greenwich, 1800 East Putnam Ave. between 10am and 6pm, Sept. 17th-21st with the goods and walk out with a wad of cash.
