Just an FYI coinflation has an app for smartphones. I like to use it on the fly what it would be worth.
Kids got into it now and dig thought he change bin at the house, and now at the grandparents. Took my phone and the app with them over the holidays. They were a bit sneaky and asked if they could "trade out" quarters with the grandparents. The grandparents are not preppers despite my attempts. Think they came away with 1/2 a roll or so. The kids kept the silver, told me "finders keepers". +1 for them thinking ahead. They are 10/11
