How many sides does a coin have?

Real=2
Figure of speech =unlimited
 
A cylinder has 2 bases and 1 curved surface, no vertices and technically does not have any edges.
Because a cylinder has a curved surface, it is technically not a polyhedron. The terms "faces" and "edges" only apply to polyhedra which have flat surfaces, straight edges and vertices.
 
I guess there are technically no sides on a coin, but I'll say several dozen (at least 4 dozen) sides because of all the grooves on the side. :D
 
Just doing my part to help this thread get to four pages...

Sometime when I'm bored, I may waste some time and count all of the ridges on a quarter.


dimes, 118; quarters, 119; half dollars, 150; dollar, 198; Susan B. Anthony dollar, 133
 
Thanks Magnethead. Since a quarter has 119 ridges, and we assume each ridge has two sides, that's 238 sides before adding the head and tail sides.

So my final answer is 240. :D
