I've seen it happen once.

Happens almost everytime. After the edge lands first, the penny eventually falls to one side or the other.
It just took me about fifty attempts before I got it.
In order for it to land on anything but its edge it must land with one face perfectly flush to the ground, ie the penny at an exact angle of 180 degrees. The chance of this is zero.
How close are you to the equator?
Depends

What if it lands on a small bump that hits the flat side?

What if the flat side isn't flat.
About the same as this.
I once had a piece of toast pop out of the toaster and fall through the thin space between the counter and the oven.
The space was barely wider than the piece of toast.
A penny has an edge on every side. Regardless of how it lands, it is landing on its edge.
I once had a dream that a hamburger was eating ME!
"it lands on it is edge"?

A dropped penny can land on one of three possibilities: heads, tails, or edge. So the odds are 1 in 3.
Depends if the plane takes off or not.
Depends on if you are trying on not.

I've seen flipped coins spin around and stop on their edge, maybe 1 in 1000 or so chance (particularly a nickel).
The research has been done for a nickel.

Probability of a tossed coin landing on edge
[quote[An experiment is reported in which an object which can rest in multiple stable configurations is dropped with randomized initial conditions from a height onto a flat surface. The effect of varying the object's shape on the probability of landing in the less stable configuration is measured. A dynamical model of the experiment is introduced and solved by numerical simulations. Results of the experiments and simulations are in good agreement, confirming that the model incorporates the essential features of the dynamics of the tossing experiment. Extrapolations based on the model suggest that the probability of an American nickel landing on edge is approximately 1 in 6000 tosses. [/quote]

Ha ha ha ha!The same thing happened to me this yeaar,

I think it is still there.
