This is a common marking on gold-plated items that indicates the item is plated with a layer of 100 mills of pure gold. However, the actual amount of gold in the item is only a minimal fraction of that, often just a few microns thick. It is not considered a meaningful measurement of gold content and is primarily used for decorative or promotional purposes.
This means that the item is not actually made of pure gold. "100 Mills" denotes the thickness of the plating in millionths of an inch, and "999 Fine Gold" is used as a marketing term to imply high quality. In reality, the item contains a minimal amount of gold and is mainly composed of base metals.
The key there is 100 mills. That means the bar is plated with a layer of gold that is 100 millionths of an inch think. Many sellers will use the term clad rather than played, however both mean the same thing. The value of the actual gold is around $0.02. However no gold company will touch these. It cost more to remove the gold plating than the value of the gold. So these bars are only worth their collectible value and have no actual previous metal value.
1 troy ounce = 31.1035 g "pure" (.999) gold
100 mills is merely a thin plating and has a very low value because the amount of gold is very small. I would not advise anyone to spend their money on such coins.
".999 silver" does not signify the weight. It signifies the purity. .999 is the same as 99.9%. But silver bullion comes in half-troy oz rounds, 1 troy oz rounds or bars, 5, 10, 12, 20, 50, 100, and 1000 troy oz bars. 12 troy oz=1 troy lb. 1 troy oz=31.1034768 g, as opposed to the oz, which weighs 28.3495231 g.

.999 is a measure of the gold's purity, not its weight. .999 Fine means it is 99.9%, or 999/1000, pure gold
