Moolah Coin 28

When I found the gold coin, I was elated. It was a beautiful piece with a very intricate design of a Martian on one side and what looked like some ancient writing on the other. The shopkeeper told me it was worth a lot of money and that I should be careful with it. I took the coin home and showed it to my wife. She immediately wanted to know where I got it and how much I paid for it. After telling her the story, she said that we should keep it in our safe just in case something happened to me since Mars is so far away from Earth. A few days later, our daughter came running into the house excitedly clutching something in her hand. When we asked her what she had, she opened up her palm to reveal another gold coin - identical to mine! We were all baffled as to where she could have gotten such a thing but eventually concluded that maybe there are more of these coins out there waiting to be discovered... by intrepid explorers like us!
