    Not a picture but the entire coin is the moon. Each side of the coin represents one half of the moon. Since the coin has two sides, the entire moon is on the coin. I picked this up at the rock, gem, mineral and fossil show that I went to two weeks ago.
    The only problem is I can’t tell the obverse from the reverse. LOL It was overpriced in my opinion but it was one of those things I just had to have. The images on the coin are an supposed to be an exact match to the moon.

    Well, it's sure not a very clear map of the Moon - not sure what they were shooting for with all those little bumps - but I see Tycho and Copernicus craters on the second image, so I'm guessing they consider that the "obverse". And it's oriented upside-down, at least for those of us in the Northern Hemisphere. ;)

    I just wouldn’t know that. I had to add extra light for the top photo as that side is a little darker than the other.

    From earth, all humans, ever, have only seen one side of the moon. The earth and our moon are in a synchronous orbit. The moon does not appear to rotate to earth. It's rotation is aligned with the rotation of earth.

    What @-jeffB posted tells us that the named craters are the ones we see every single night, and day. Most people would probably refer to that side as the 'front' or obverse for a coin.

    As the swimmer said we only see one face due to the moon being tidally locked with the earth. Here is a free photo of the far side, or as the Floyd said, the "dark side".

    The second photo looks like the side that we see.

    Minor correction - it's rotation is synchronized with its revolution around earth. Tidally locked, as @ksmooter61 said. It rotates once for every ~29 day revolution around earth, thus keeping one side always facing us.

    I had a map of the moon on my bedroom wall as a kid. I loved the fact that two craters have my last name except both are spelled differently than mine.

    At first glance, it looks like a corroded wreck. I'm not sure I would've recognized its lunar attributes, had I not been told what it was.
