The penny example is bad. A non American cannot know and frankly many are plausible. It also confuses memory of a thing with repetition reinforcing learning.

Sorry, I think this post is crap

Also, isn't the correct penny A? I've never seen one in real life, but if wikipedia is to believed it says "In God We Trust" at the top, not "United States of America".

Even googling "1978 penny" shows the one from A.

Just FYI: We don't even know why we have them anymore. For the last 30 years or so, pennies have been worth less than their raw materials. They're so worthless, most people have more of them in their furniture or under their car seats than they do in their wallets.
