How many shorted turns does the metal can emulate, and what is the mutual coupling between your winding and the can? If the result is useful, I suggest an immediate patent.

I wind coils around a metal coffee can. The
metal increases the inductance just as a ferrite
core would, requiring less turns of wire.
