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).
The color looks a bit different, but it's difficult to describe. The easiest way is by weight. If it is 50% silver, it should weigh 5.8319 grams; if it is nickel, it should weigh 5.0600 grams.
Canadian nickels have never contained any silver.
Their composition depends on the date:
No. There are two versions of the 1968 Quarter. One with 50% silver and one made of nickel.
Some are 50% silver/50% copper, others are pure nickel. The easiest way to tell the difference is that the nickel version is magnetic.
Being that both the 80% and 50% versions weigh the same, there is no simple method to tell the two apart. Given the relatively low value either way, testing costs more than they're worth.
By the date. The Jefferson nickels were made from a copper, silver and manganese alloy during World War II: 1942-1945
Nickel is a silver-colored metal that tends to have a more yellowish tint compared to silver. Additionally, nickel is not as shiny as silver and is heavier than silver. You can also check for markings on the metal to confirm the material.
There are two varieties of the 1968 Canadian quarter. One is 50% silver with 50% copper, and the other is pure nickel. The easiest way to tell them apart is with a magnet. The nickel version is magnetic, while the silver/copper version is not.
Very simply: All Buffalo nickels, regardless of date, are made of a cupronickel alloy. None of them ever contained silver.
silver is usually stamped 925
Assuming you refer to the 1981 British 25 Pence coin (Crown), it is made from a copper-nickel alloy. If you have a sterling silver Proof coin, it will state somewhere on the packaging that the coin is made from sterling silver.
It isn't. No 1969 quarters are silver. Silver quarters were only made in 1964 and before. All quarters from 1965-present are copper-nickel. There isn't even a 1969 commemorative quarter that was struck in silver. There is no possible way for it to be silver.
By the color, obviously. NIckel plated flutes are slightly golden and well, silver plated, they have silver color.
the edges will be all silver instead of the a normal quarter that is copper with nickel platingYes, but ...The most general way is by date. All quarters dated 1964 and earlier are made of 90% silver alloy, and all circulating quarters dated 1965 and later are made of copper-nickel clad composition (NOT nickel plating; there's a major difference). The US has struck quarters in silver since 1965, but all of these carry an S mint mark and were made for inclusion in special collectors' sets. Specifically, some 1776-1976 Bicentennial quarters were made of a 40% silver clad composition, and since 1992 90% silver composition has been used in special "Prestige" proof coins.
The easy way is by the dates. Halves made in 1964 or before are 90% silver and 10% copper. Kennedy halves from 1965 to 1970 are only 40% silver. All regular issue halves from 1971 to date are copper-nickel.
If I was to sell mine I would want at lest $2000. Thats why you don't ask other people. You tell them what its worth to you!
I have yet to find any Alpaca that is sterling. It is made from nickel and other varies metals. Alpaca was made for people in areas that could not afford sterling or gold jewelry. You can magnet test it......the easiest way to tell. :)
