cheapest way is to soak them in water, distilled water is best. each day take them out and pat dry or use a soft brush. you can also freeze them in water then thaw, the expansoin can lift some material from the coin. It takes time but it's a cheap and safe way to clean coins

Well we found out the item..it appears we had some old rust away sprays that take a while to remove the rust and it was a round piece of metal...it sucks but we will learn as much as we can when doing this stuff..however we used salt/vinegar to shine the coins and hot water for now to clean them off...it's doing enough to make it sort of legible
