Abstract
A coin roll opener for opening a plastic wrapper packaging about coins in the form of a roll includes an insert having an elongated, relatively narrow upper surface and at least one corner formed by intersection of the elongated upper surface with a second surface of the insert. In preferred embodiments, the insert is mounted to extend from a body, and two opposed corners are provided. A method for opening a coin roll with the device is also described, whereby a coin roll is rotated in engagement with the corner for initiation of an opening in the plastic wrapper packaging for release of coins.
