The .999 Fine Silver Enriched means that this is not pure silver, but has a heavy silver content. The purity rate for silver bars and rounds is much the same, but they come in 3 typical forms other than jewelry or forks and spoons. Bars and rounds at .999 fine is a higher grade of purity than collectible silver coins, which are typically 90% fine or .900, or sterling silver, which is 92.5% fine or .925.
Enriched means that vitamins or minerals have been added to the food. The vitamins and minerals are added to replace the original vitamins and minerals that were lost during the refining process. For example, if the food originally had iron, but the iron was lost during the refining process, the food will be 'enriched' to add the iron back into the food. Consumers often think enriched means 'added vitamins and minerals'. This assumption is incorrect.
