My advice would be to stick to coins with recognizable toning patterns. Like bag, textile, album and tab toning. That's not to say the really talented doctors can't mimic those patterns... but at least they know how to stabilize the coin after they're done (another use for acetone)

Do a search for a thread of mine from a while back on -Various Methods to Detect Artificially Toned Coins-.
