Bang Ring: A brass ring that is used to open any locking coin or locking coin set. By using such a device to open your gimmicked coins rather than shaking them in a glass, your coins will last a lifetime.
Helpful hint from Mimesis Magic : If you must seperate your locking coin(s) by shaking them in a "glass" method -- use a plastic tumbler or a soft (but firm) plastic drinking cup.
This bang ring unlocks the dime insert from the penny shell (The locking 11 Cent trick or locking Dime to Penny).
