OK not quite but, I did have 50 cents put into my white water for whatever reason.

Nah, not coin op, like MMr, white water had no coin mechs.

With all these 50 cent drop someone was just looking to give tips to games they liked I think.

i think it might have been, kind of a "thanks for bringing this". Or its just the horribly corrupt Illinois political machine checking to see who fails to claim the income so they can throw the book at us.
