Make this Numismatic Mistake and Lose Thousands!
There is rarely a scenario in which one inexpensive, simple change can result in thousands of dollars in savings. When it comes to coin collecting, however, there is such a scenario.

In the video above I explain exactly what the problem with PVC is and how you can prevent it from destroying your coin collection. Seriously, this is one you do not want to skip.
