There is only one of this series in the MOGH guide. What makes these second generation is the date. The one in the MOGH has 1996-97 on the face while this is second series -- all different subjects -- with 1997 on them. One is a "crawfish" or "mudbug" while the earlier one is a "white shrimp," a mainstay along the coast's economic seafood species. Like I said in my first post, these are different with the exception of the one that represents "historic landmarks in Biloxi." Perhaps, someone has additional information about these coins that can help us all know more about them. The "masks" represents a salute to Gulf Coast Mardi Gras and the "Magnolia" is the state of Mississippi's official flower. Thanks
