I think this currency is only redeemable in the Cantina bar. Mark, aka Diablo2003, created these pieces of Imperial currency for the Star Wars Fan Days 2007 where he was a guest artist.
There's a lot of artwork out there most as posters, lithographs or prints so I wanted to do something different. While watching The original Star Wars I realized that talk of money is thrown around quite a lot but you never actually see it (other than Han flipping the bartender a coin after shooting Greedo). I thought it would be cool to design a piece of Imperial currency as I saw it. I designed it mostly after American money but used some European influences as well.I hope Darth Vader can keep his money in this economy.
