I'd like to view the optimum frequency as a compromise between
a) The max f possible. This is sensible until the force flattens out. That is a property of the coin, i.e. its inductance and resistance. This max sensible f could be established by a low power measurement.
and
b) The losses in the caps, wiring, switch and the coil. Higher f implies larger currents and bigger losses. These losses are a property of the driving circuitry. Preferably these losses are still low at the "sensible f" from a).
