A lot of people have posted about coinstar finds but in all my years of working at a Kroger I have gotten a lot more coins by talking to the people using the coinstar. Countless times I have offered to purchase coins from other countries only to be told I can have them for free and I recently took all my Canadian coins and sold them at 90 percent for over 200 dollares.. I have also found a lot of coins including silver coins in the trash can near the machine.
