The mass of an 80% silver centennial quarter is 5.83 grams, whereas the mass of a 50% silver centennial quarter is 5.05 grams. ------------- I don't think that this is correct. The nickel quarter made in 1968-1999 is indeed 5.05g, but the 80% and 50% silver quarters are each listed as 5.83g. Since Silver and Copper (the other componant of Canadian silver coins) have different densities (10.49g/cm3 for Silver and 8.96g/cm3 for Copper), the 80% and 50% coins should have either different weights or different volumes. Doing the math, if an 80% coin had a weight of 5.83g, it should have a volume of 0.5725cm3; a 50% coin with a volume of 0.5725cm3 should then have a weight of 5.57g. Alternatively, if the 50% coin has the same 5.83g weight, it should have a volume of 0.5994cm3; this implies, assuming that the coins have the same diameter, that the 50% should be about 5% thicker, which I think would be tough to discern without a fairly accurate micrometer (and, of course, a knowledge of how thick the 80% coin is meant to be).

How do you tell a silver nickel from a regular nickel?
You can differentiate between a silver nickel and a regular nickel by checking the date on the coin. If the date is 1942-1945, it could be a silver nickel as those were made with silver during World War II. Regular nickels are made primarily of copper and nickel. You can also use a magnet to check - silver nickels are not magnetic, while regular nickels are.

How do you tell the difference between sterling and nickel silver?
Nickel silver is an alloy of nickel, copper, and zinc, while sterling silver is an alloy of silver and copper.

Sterling silver will also have a brighter appearance and may tarnish less than nickel silver.
What is the silver content of a 1958 Canadian 25 cent coin?

How do you tell if a 1942-1945 nickel is silver or not?
Nickels minted between 1942-1945 during World War II were made with a composition of 35% silver because of nickel shortages. You can check the edge of the coin for a large "P," "D," or "S" mintmark above Monticello to distinguish these silver nickels from regular ones.
Is there nickel in sterling silver 925?
It depends on the manufacturer, some do use nickel as a filler, some use copper, and other metals as a filler, but if it says 925 on it I wouldn't worry too much about it.
