If silver or gold coins had characteristic resonant frequencies then it ought to be possible to scan large areas of sea floor for the loot.
Maybe you find something maybe not but at least you have a good excuse to go fishing.

Step 1: drain the oceans so that the radar signals will propagate...

They do (it's related to their size), but sea water doesn't pass thoese frequencies well.

Step 2: Drain Usenet of all trolls.

What do you mean by resonant frequency? Acoustic? Electromagnetic/RF? Nuclear? They have all three. But all that seawater gets in the way.

The navy uses 20 - 30 kilohertz sonar without even a resonance effect to exploit.
The goal isn't to get every gold bar out of the deep ocean, just what can be detected from 20 - 30 meters.
