The coins are not made of pure silver, but are an inexpensive metal clad alloy plated with about a 10,000th of an inch of silver valued at about 1.4 cents. This same plating (thin coating over the complete surface of the coin) is .999 pure silver, again valued at about 1.4 cents. Anytime you see something advertised as "10 mil' or 100 mil" the "mil" refers to thickness.
