Do you really think cleaning it off with water is that bad? It's been subject to abrasive soil, weather, elements, etc., for over 100 years. I would say most coins I find aren't identifiable until I soak the crud off. What would you suggest as an alternative? Not trying to be confrontational, I'm sincerely asking... I'd have a ton of coins with caked on dirt without knowing what they were unless I soaked the mud off. Much better than rubbing it off I'd say!
