18" 1980's Jim Beam 1934 Duesenberg Model J Porcelain Decanter Sealed and Box

This is a 1980's Jim Beam's Model "J" Duesenburg Bottle A.C.D. Museum Edition decanter. It is a 1934 Duesenburg Town Car. Needed some help with some information on this. I wanted to sell this and can't find alot of information on it, I am assuming it is really rare. I have found a light blue one just like it on on ebay for $30 or so but mine is dark blue. Also I have the box, paper work and it is sealed but does not have alcohol in it, I am hoping having all of that increases the price. And the only thing I can figure about the seal being sealed and no alcohol is it could of been a display, I have read that somewhere before. I am saying the 80's because on the bottom it says china and 198- something either 80 or 84 but inside the packet of information it says that this "decanter has officially been accepted as the mascot of "Auburn "82"- the 27th Auburn-Cord-Duesenberg Festival", so what ever that means.

 It is is great condition. No rust or dents. It does have a few light  scratches, but nothing major. A few that I saw was on the front extra tire chrome, on the driver side/ passanger doors, and the wind shield. Other than that I don't see anything wrong with it.

Let me know what you think or where can I go to get some help. Thanks
