As to the Penny (more properly called "Cent" ) How many of us know that the Obverse side, showing the Lincoln Memorial, you can see the Lincoln Statue inside of the building. You may have to look using a magnifier, but it's there..
A great Bar or Party trick.. Ask folks to find the "Second picture of Lincoln " on the penny...... or something like that.. UW, Ralph Ahseln "Oblio"
