Just for fun I've been looking at silver ingots including art bars that are ~1 ounce. I keep running into the following wording that has me a little suspicious of the true contents of the bar:

The bar weighs 26grms and struck in 100mil .999 silver-clad and measures 1.96" x 1.14".

What is this sentence really telling me?
What is 100mil .999 silver-clad?

100mil .999 silver-clad

100mil is the thickness of the .999 fine silver plate. The core material (bulf of the weight) is not silver.

mil [1]
a unit of distance equal to 0.001 inch: a "milli-inch," in other words. Mils are used, primarily in the U.S., to express small distances and tolerances in engineering work. One mil is exactly 25.4 microns, just as one inch is exactly 25.4 millimeters. This unit is also called the thou. With the increasing use of metric units in the U.S., many machinists now avoid the use of "mil" because that term is also a handy slang for the millimeter.

100 mil silver clad means it is a silver plated piece of base metal, do not buy it for silver. Buy it only if you like the design.

Additionally, just FYI, a troy ounce weighs approximately 31.1g, so I don't know why someone would make a bar weighing only 26 grams.

I was aware. These are apparently replicas of LE 1 oz silver bars. Changing the core to base metal while retaining size must have lowered the weight.

Fake ingot. Base metal with silver plating. Don't waste your money because it's not even worth the shipping costs.

Also be warned that although as WoodenJefferson said a Mil is a thousandth of an inch, these companies that have been making the silver and gold plated replica coins have been using the term Mil to stand for a MILLIONTH of an inch! A true 100 Mil plating would actually be a tenth of an inch thick or 2.5 mm! A very substantial layer! (A copy silver dollar with a true 100 mill silver plating would be over 5 mm thick just from the plating! The maximum size that an NGC slab can hold is 4 mm thick.) A 100 Mil thick plating with these new companies definitions is just a ten thousandth of an inch thick, or half the thickness of the plating of the copper on a zinc cent.

Correct. A base metal copy (using copper, nickel or a coppernickel alloy) of a pure silver object will only weigh 85.7% as much. So a copy of a 1 oz silver bar would only weigh 26.66 grams.

Well, here's one that had me confused, I got this in the mail and I was pretty darn sure that it wasn't actually pure silver but it is the same size and weight as a 1 troy ounce bar. Any thoughts?

Last I checked, 15 Grains was roughly 0.03 Troy ounces, but like I said it has the size and weight.

So 0.03, would that just be enough to be plated?
