Sterling Silver Purity

Stirling Silver is a metal alloy comprised of 92.5% silver and 7.5% of other metals by weight.   This is established by the sterling silver standard where the millesimal fineness has a minimum of 925.  This is in contrast to Fine Silver which is 99.9% pure silver.

Silver Calculator Functions: 

• Bullion Silver Value - Computes the value of bullion (.999) silver based on weight and the current spot price.
• Silver Alloy (scrap) Value - This computes the value of scrap silver base on the purity, weight and current spot price.
• Junk Silver Value - This computes the value of junk silver (U.S. silver coins) based on the face value of the coins and the current spot price 
• Junk Silver Coin Count - This computes the value of junk silver coins.  It let's the user enter the number of different coins to compute the value.
• Clad Silver Value- This computes the value of U.S. silver half dollars between 1965 and 1970 based on the Face Value, a Clad Factor and the current SPOT price,
• Spot Price in U.S. dollars per gram: $1.095 per gram
• Silver Spot Price in U.S. dollars per troy ounce: $34.06 per troy ounce
• Percent Silver in Sterling Silver: 92.5 %
• Percent Silver in Fine Silver: 99.9 %

Computing Silver Value

The Value of Silver Alloy is four step process:

1.  The weight of the pure silver is established based on the input weight and the purity percentage.
2.  The current value of the pure silver is established by multiplying the weight of the pure silver by the current silver spot price.
3.  The value of the silver alloy is reduced by the fee paid to the refiner.
4.  The value of the silver alloy is reduced by the fee paid to the retailer.

The result is the price that can be given to the seller of the metal while paying the refiner and making the profit identified. 

The weight can be in Troy ounces, pennyweight or grams. vCalc converts the weight into Troy Ounces and then fetches the current spot price for an ounce of silver. It then multiplies the weight of the pure silver content against the spot price and scrap discount percentage to give the silver's value. discount(scrap) = 1 - scrap

Note: scrap free and profit are both a percentage.
