I refer to these pieces as tools. Two of my images use four (4) pieces (two sets of tools) for illustrative purposes ONLY, so that all four denominations can be viewed in one single image. Then center the black hard plastic Coin Wrap Sealer Tool on the open/uncrimped end of the roll and twist while pressing towards the stacked coins/crimped end.
Twist-n-Crimp Penny, Nickel, Dime, Quarter Roll Crimper includes 2pcsWill easily crimp the end of your pre crimped coin wrapper rolls. Instructions:1. First thing is to fill an already crimped on one end coin roll wrapper (Called a shotgun coin roll) with your choice of coin with the correct amount. 2. Second, place the selected coin Crimper device overthe open end of the wrapper end to be crimped. 3. Finally, just slowly turn and push very slightly atthe same time, aprox. 5-7 complete turns. 4. Do not force the crimper as this willonly crush the paper wrapper.
This Coin Wrapper & Crimp Set was designed and tested from scratch to eliminate those problems. I print these myself. I made all files and developed the function of these coin rollers for coin collectors such as myself.
