A penny is an alloy because it is a mixture of different metals
A penny is not an alloy because it's not really a "mixture" of zinc and copper. Post-1983 pennies are 97.5% zinc core with the remaining 2.5% of copper layer on top. Search for "Make a brass penny" to see how one makes a penny an alloy by heating it up enough to melt and mix the metals, making the penny appear gold.

How can a penny float?
A penny will not float in water, mainly because it is denser than water. When the penny is placed in water, it displaces a volume of water equal to its own volume. Since the penny weighs more than the water it displaces, it will sink.So, in order for the penny to float, you must find a liquid that is denser than solid copper -- or whatever metal or alloy a penny is made of. Mercury -- which is a liquid at room temperature -- is denser than copper. Hence, a penny will float in mercury.Possibly surface tension may allow it to float.
