Checking a bullion item’s mass (weight) with its volume (size) is called a density test and is the oldest and most common method to inspect bullion. For example, to check the mass of a silver Mexican Libertad coin, simply place the coin on top of a known good Libertad coin to ensure the diameter matches and then next to each other to ensure the coins’ thickness (height) matches. Then weigh both coins to ensure the mass is the same. Unless you find obvious inconsistencies the coins would have passed the density test.

Through ECM we can offer walk-in customers a quicker alternative to a full DUX test. Please note that an ECM Check does not come with a test report, tamper proof seals or online verification which are included as part of a full DUX Test.
