So, here are some givens:
We search sealed boxes of machine wrapped coins.
We know that one end of the wrapper is pre-formed and loaded in to the counting machine, the coins are counted/dispensed and in a separate step, the crimper presses the roll tight, and applies the final roll crimp.
We also know that many coins are damaged in this process - but I'll say 1 in 10 rolls for this example.
Now, with 20 coins per roll, there is a 1 in 10 chance of the open end coin getting damaged.
Each time the coin is subject to our "catch and release" it gets stored in the bank vault until it goes back to the vendor, where it is mechanically sorted, counted and rolled again, increasing the chance of more damage.
