Hydro Duck coin-op Arcade Machine

[Charles]

Does anyone know of a price guide having a Hydro Duck Arcade machine. I cannot find any guide with this machine and trying to determine a value. I've never seen one offered before at auction or on ebaay. The machine is in good conditon, complete and but needs some cleaning. The graphics, cabinet is 100% original. I appeciate any helpful information.
Thank you, Hydro Duck Coin op Arcade Machine
