I found this Argosy Casino, Kansas City, MO $5 Grand Opening some time ago but have been able to discover much about it. The Chip Guides does not have any information about the riverboat -- I believe is was named Argosy IV or Argosy V. It has a hologram on one side, and Grand Opening 2003. It's seen a lot of play, but still in satisfactory shape to own. There is an Argosy Casino in Kansas City, MO but has a land-based facade, and all modern chips. However, no mention about other Argosy casinos that came before this one was put in place.

FOUND THIS ON INTERNET --
Hard times hit the Argosy IV in 2014, when it was forced to close by Iowa regulators that found the casino in violation of a state requirement that casinos partner with a licensed, local nonprofit organization. After it shut down that July, the boat was sold off and sent to a shipyard in Wood River, Illinois.Nov 17, 2018

And This New Report From India

PANAJI, India -- The Argosy IV riverboat, a floating casino that was docked in Sioux City from 2004 to 2014, has been sold off and moved to western India.
The Times of India reported Friday that the boat, which was moved from Sioux City four years ago to a shipyard in Illinois, was purchased for a reported $850,000 by the Pride Group of Casinos and Hotels. Pride Group plans to use the Argosy IV as a substitute riverboat casino when two of its other boat casinos, Casino Pride I and Casino Pride II, are dry-docked for repairs in the port city of Ratnagiri.
