Unfortunately no, I don't think that's possible.

If you have bought something using gold/sheriff stars that you have earned in-game, there's no way to refund them.

Only way to get them back is if you have bought gold/sheriff stars through in-app purchases, but it will require you to start a new game and choose "Restore Purchases" in the settings.
