I cleaned a sovereign once. I won't usually but this one was really grim... like it had lived a large portion of its life stuck down a squaddies undercrackers. It wasn't a rare one so I thought what the hell. I read on this very forum about a method of putting a dab of neat washing up liquid on each side and rubbing it gently between your forefinger and thumb, so as you can't feel the faces of coin itself, rather rub only the viscous liquid into the coin. I did that until the green gloop turned brown, then I ran it under the tap and then I patted it dry with a paper towel. It wasn't gleaming spotless, but it was a big improvement on its original condition which I never really want to touch before. I want to emphasise again that it was a bog standard bullion sov. Almost literally.
