"The coin, made up of chrome and nickel, weighs three grams with the inscription 'galactos' and the year of issue 2004. It will be identified by the letter G with two parallel lines like the US dollar."
Oh, like they're going to go for this. I had hoped for more imagination.
Which reminds me: The mainstream media doesn't know what the word "intergalactic" means. "Intergalactic" is routinely used when what's actually meant is "interstellar," which refers to beings/phenomena originating in other star systems in our galaxy. Nuts-and-bolts spaceships from some other planet, should they arrive, will likely be interstellar, not intergalactic. (The preceding two sentences should be read aloud in your best Carl Sagan voice.)
An intergalactic expedition isn't impossible, but to be practical it would almost certainly have to hinge on arcane "warp drive" physics. But "mere" star-to-star journeys can be accomplished with brute-force propulsion; if pressed, we could construct a crewed interstellar vehicle using today's technology.
(In fact, we could have gotten a good start on this decades ago -- but we decided to spend the money on nuclear bombs, the "War on Drugs" and other, equally inspiring endeavors instead . . .)
