Without proper care, even the simple act of removing a coin from a holder carries the risk of damage. The term flip rub refers to wear or damage caused by rubbing a coin against the surfaces of a vinyl or plastic holder. Any dirt or contamination that comes between a coin and a holder acts as an abrasive, and any movement of the coin against the holder may damage the surfaces of the coin. Therefore, the less often a coin is removed from or inserted into a holder, the better.

That’s why it’s always a good idea to ask permission to remove a coin from a holder to examine it. The dealer may prefer to remove or insert the coin or may refuse your request. Don’t be offended; the dealer may simply want to protect the coin. On the other hand, be prepared to make a purchase decision under less-than-optimal conditions.
