Is there a silver ratio if there's a golden ratio?
yes, if the golden ratio is ((square root 5) +1)/2, then the silver ratio is (square root 2) +1. as the golden ratio is represented by phi, the silver ratio is represented by deltas. as two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one, two quantities are in the silver ratio if the ratio between the sum of the smaller plus twice the larger of those quantities and the larger one is the same as the ratio between the larger one and the smaller.
What materials are used in a 1962 quarter?
The same as in all silver coins minted in up to 1964 - an alloy of 90% silver and 10% copper. Due to the rising price of silver, in 1965 the Mint changed the composition of the dime and quarter to a 3-layer "sandwich" consisting of outer layers of 25% nickel / 75% copper bonded to a pure copper core. Halves were changed to outer layers of 80% silver bonded to a core of 40% silver. Unfortunately the price of silver continued to rise and so many halves were melted that they effectively disappeared from circulation. In 1971 the Mint belatedly switch them to the same composition as dimes and quarters but it was too late to restore the denomination. The new Sacagawea and Presidential Series dollars are made of a manganese-brass-copper sandwich, giving them a golden appearance.
How much silver is in a Roosevelt dime?
Roosevelt dimes dated 1946 to 1964 are made of 90% silver and 10% copper. They contain about 0.0714 troy ounces of silver (or about 2.22 grams). So to find their melt value, multiply the price of one ounce of silver by 0.0714. For example, if the price of silver is $15 per ounce, the coins would contain about 0.0714 * 15 = $1.07 worth of silver.Depending on the coin's date, mint mark, and condition it may be worth more to a collector.Dimes dated 1965 and later don't contain any silver at all, just copper and nickel.
How much is a 1964 pure silver dime worth?
The U.S. never made 100% silver coins for circulation. The metal would be too soft for daily use. All silver coins had at least 10% copper in them. Dimes dated 1964 and earlier contain about 0.07 ounces of silver. The price of silver changes so you'd need to search on terms such as SPOT PRICE SILVER to get the most current value, then multiply the price per ounce by 0.07. For example, at $14/oz a 1964 dime contains about $1 worth of silver.
