Also Sharon, you can google "cleaning ancient/antique coins" and you'll get some good information there.
When I was studying archaeology those things weren't mentioned but now I'm studying archaeological conservation, and those guys are a lot stricter :lol:
You have to know that acid free paper and cardboard isn't really acid free. Certain substances were added to the paper/cardboard to neutralise the acids, but after years these substances will stop working. So you might want to replace it after some years.
