Watched a Roman coin go from a gray lump to showing a face after 20 minutes in distilled water
My buddy found it at a dig site in Bath last spring and it sat in a box looking like a pebble until he finally soaked it. The crust just lifted off and you could see the emperor's profile clear as day, which got me wondering how much stuff in museum storage is hiding details like that. Anyone else seen a find totally change after a simple soak?
