A Monster Box is a plastic container used to simplify the storage and security of bullion coins. Monster boxes are used by the US Mint, the Canadian Mint, the Austrian Mint, the Perth Mint and private mints to hold large orders of their minted coins, rounds and bars.
The coins are divided into ‘rolls’ or ‘stacks’ of coins with each roll neatly encased in a plastic tube.
The tubes are arranged in the monster box casing and typically make up a total of 500 coins, with the rolls stacked vertically side-by-side next to each other to form a symmetric layout of rows. For some coin releases, a smaller monster box containing 250 coins is used.
The lid of the box features a raised seal with the logo of the mint issuing the coins, and an untampered-with box is sealed with tape, also bearing official information from the issuing mint.
Investors looking for the lowest dealer premiums that buy silver in bulk will seek out a Monster Box. When you buy a monster box of silver you will often get the best price.
