If I were you I'd bury them about where you found the other one in the other post! :blink:

I didn't mean to be so negative.

It looks like they've be stored somewhere damp, and verdigris has spread onto most of them.

Melody as Chris rightly pointed out the green substance is "verdigris" (a green corrosive growth resulting from dampness).

It is quite hard to remove without damaging the coin, it is like a disease for coins. It is an oxidation coating that affects copper and bronze.

Never store coins affected with verdigris with other coins as it will spread.

Since the coins in question in good condition would be collectable (albeit not too valuable) in this condition I too would suggest getting rid of them because you don't want it spreading to your other coins.

Well that will be my dad storing his stuff in the cellar then :P

He wasnt a serious collector, just a gatherer of bits I suppose.

Those ones are all in a box together anyway.
