The few coins I have bothered to examine (which you have posted) all look like they have been 'electrocuted' by someone that practices the evil arts In this condition they are of little or no value to most serious collectors You would be better off if they had simply drilled holes in them
In the event you are unfamiliar with what FR refers to, here's the entry for electrolysis from Numiswiki:
Electrolysis Also referred to as zapping, nuking, or frying; electrolysis is a poor method for cleaning coins using electricity. It can be useful if done properly by a practiced expert but as a tool used by amateurs the results are usually dismal.
