They are just art items, novelty stuff that cost maybe $1 total to produce. The coating is so thin the actual amount of silver is maybe one gram.

What does 100 mills 999 fine silver mean?
They *are* clad in 0.999 silver, but the real question is how thick is the cladding. Part of the problem is that "100 Mills" has absolutely no legal or engineering meaning - they may as well be stamped "100 Rhubarbs". 'Mil' (with one letter 'l') is a term used in engineering (in the UK at least) to mean 1/1000 of an inch - but if the cladding were actually 100 *mils* thick, that would be 1/10 inch (about 2.5mm); seeing as a 1oz bar of REAL silver is only about 2.5mm thick, that would mean that one of these '100 Mills' bars would have to be clad in TWO ounces of silver. Obviously they're not, or the producers would go bust very quickly. If we assume that 'Mill' is actually short for 'Millionth' (of an inch), it makes far more sense. The thickness of cladding would then be 0.0001 inches (0.0025mm) - which is about normal for electro-plated items. Each side of the bar would require 1/1000 of an ounce to plate, so the whole bar would take 1/500 oz. At current prices ($30/oz) that means that each bar contains about 6 cents worth of silver.
