In 1997, "Captain Bill" Sheehan founded Hackensack Riverkeeper, an advocacy organization dedicated to protecting and conserving the Hackensack River estuary, which includes Secaucus. See if the objects found at the Secaucus ROADSHOW floated upstream or downstream in the last 15 years: A circa 1900 folk art ship model was bought at a yard sale in 1996, valued at $5,000 to $7,000, and now is sinking fast to $ 300 to $500; but a gaming table bought for $25 and appraised at $200, 000 to $300,000 now could score $400,000 to $600,000.
