Hi Tony, What you have is called the Greentown Dolphin with beaded edge. It should have a lid. These have been reproduced and the easiest way to tell is to take your finger and stick it down into the dish, if it goes almost the whole way it is original, if your finger does not, but say only half way, its a reproduction, although I don't believe the beaded edge style was reproduced. As to the color it appears to be what is known as chocolate glass. Jacob Rosenthal came to Greentown (which is collectors name for "The Indiana Tumbler & Goblet Co.) in 1900 where he invented chocolate glass. Hope this helps, Terry in Iowa
