Man those are corrodded! I don't know where I've read it before here...

I've been reading that sticking the pennies in a potato cleans them up good... use your Charter Member super powers and check it out on the Search Option...
For coins in that shape they will have to soak a long long time in olive oil. Try the hot peroxide after you wash all the oil off of them. And if that don't work there is still a few other things you can try. Good luck

I use the potato method all the time. Just make sure to remove them and rinse them off daily and then when you are done rub a little beeswax on the coins to help shine them up. With a coin like that it will probably take several days.
