Coin wrappers are the paper tubes having the finished crimp at one of the ends of tube and the opposite end is wide open. Coins are inserted in the wrapper through the open end of tube in order to form a stack of coins. Coin stack adjoins the crimped end wrapper in order to prevent the coins from falling from the wrapper as it is being filled.
The coin wrappers are designed in such a way that it holds specific number of coins such as denomination, etc. When coin wrapper is filled, the tube's open-end projects beyond the coin stack. The wrapper portion that is projecting is then folded manually over the coin stack in order to secure the coin stack inside the wrapper.
