Silver content of British Silver Coins

[Winklebury]

Hello

The percentage is the silver quality, e.g. 92.5% or .925 (over 1,000)

as the coin is about 2.8 grams, multiplied by 0.925 that makes 2.59 grams of pure silver.

As 31.1 grams (of anything) is a troy ounce, 2.59 / 31.1 = 0.08328 troy ounces, not 0.8

Dont forget swiss coins...the often overlooked little beauties of the numismatic world...unfortunately i have no books at present so dont have my list of what and how much however a quick googlefu finds this

Prior to 1968 all Swiss coins from the half franc upward contained either 83.5% silver or 90% silver. The single exception is the 5 Franc coin which was minted in silver again in 1969 (after being minted in copper nickel in 1968). Starting in 1991 a series of crown sized commemorative 20 franc coins were minted for collectors which contain just over half an ounce of silver. All silver coins shown in this calculator were minted at the Bern Mint in Switzerland and show the B mintmark

I've been buying kilo+ lots of foreign coins mainly from car boots for quite a while now and always find at least a few overlooked swiss

I know this has been here a while, but I thought I should add this.

6 shillings face value of pre-1920 .925 coins OR 11 shillings face value of post-1920/pre-1947 50% coins are (approximately) 1 Troy Oz Silver weight.

$1.40 face value of US pre-1965 .900 is 1 Troy Oz silver weight

Pre Decimal coins from South Africa, Australia and Canada tend to be .800.... Calculations to follow

** All of the above are for relatively unworn coins (these may have a higher Numismatic value then their scrap value).
For worn or slick coins you need to check weight when you buy, but these numbers will give you a rough idea**

All pre-decimal British Silver Proof coins are .925 and are also 6 shillings face value to the Troy Oz
Post decimal British Silver Proofs are also .925, but I haven't worked out if there is a simple face-value..... I don't think so
