A coin that securely holds a bitcoin private key and reveals the Bitcoin Address?
Casascius has created those, but the process was very expensive to do. He had to have a token company make a brass token with a Bitcoin logo on it. Then he had to get a hologram made that was would be harder to counterfeit. Then he had to securely get the private key onto the coin (via paper), without any mistakes (i.e., where a coin goes out without having correct amount of bitcoins on it).
He is now trying to come up with some "low security" coin manufactured using a laser engraver:

Now with a paper wallet you have the exact same ability to show off how bitcoin works (private key / Redeem, Bitcoin Address / Load). And it costs nothing more than your time and the cost to print a sheet of paper:
