Yes - this IS about coins. Bear with me.
There is so much talk about going to Mars today. One of the most fun items that I own is a genuine rock from Mars:

I enjoy showing this to my friends when they come to visit. The resulting "Oohs" and "Aahs" are generally followed by,
Friend: "is it real?"
Me: Of course.
Friend: How did you get it? How can you be sure its a real Mars rock?
Me: I am absolutely sure it is legitimate and can prove it.
Friend: "How?"
Me: I went to mars and got it for myself. I picked it up right in front of the train depot. The Martians didn't seem to mind. The ones I talked to were very friendly people, especially in the Martian railroad museum.
Friend: Uh huh.....
Well, Since I own a legitimate rock from Mars, when I saw the following
ebay item, I had to have it. This Martian coin is the size of a
Morgan dollar:


So yes, I HAVE indeed met and talked with Martians. I even had the opportunity to introduce a Martian couple to some of my friends once by saying, "I would like you to meet some Martians."
Its just my kind of mindset to wish I had been born there so could introduce myself to people as a legitimate Martian.
Mr. Musk, eat your heart out...been there...done that!
