Moolah Coin 27

When I woke up last Tuesday, I had no idea that my life was about to change forever. There, on my dresser, sat a shiny gold coin with a cute Martian engraved on it. At first I thought it was some kind of joke - why would there be a coin from Mars sitting on my dresser? But then I picked it up and felt its heft in my hand, and knew that this was no ordinary coin. I took the coin to school with me that day, showing it off to all my friends. Everyone wanted to hold it and feel its smooth surface. We were all convinced that this wasn't just any old coin - but one from another planet! It must have been left behind by some Martians during their visit to Earth... or maybe even sent here as part of an intergalactic currency exchange program! Whatever the case may be, we were sure that this little gold coin was something very special indeed.
