The US Mint ships bullion coins, including American Silver Eagle coins in bulk to authorized wholesale distributor in special packaging called a Silver Monster Box.
After minting, the US Mint packages bullion coins in plastic tubes. Each standard tube holds twenty 1 oz coins. The tubes are then fitted into the Silver Monster Box 25 tubes at a time. The tubes have a relatively snug fit to reduce movement and vibration during shipping.
Each Silver Monster Box contains 500 troy ounces. Both Government Mints and private manufacturers have adopted the practices of shipping bulk product in quantities of 500 troy ounces in Silver Monster Boxes.
A Silver Monster Box of American Eagle coins is green. Other Governments Mint use different colors to identify their Monster Boxes. Some have different colors and sizes for different series’ of coins.
For example, there are some special series’ of coins from the Perth Mint that are shipped in Monster Boxes that contain only 250 troy ounces of silver coins. Some bullion distributors have adopted the term as a way to offer yet smaller quantities, as little as 100 troy ounces, with the term Mini-Monster Box.
