How High the Silvery Moon?
The gold silver ratio is obtained simply by dividing the current gold price by the current silver price. What currency you price them in does not matter, as long as you use the same currency for each, and obviously for the same weight, so US dollars per troy ounce will work just as well as euros per kilogramme, or pounds per ounce.
When the gold:silver ratio is high it means that gold is expensive compared with silver, or the converse, that silver is cheap relative to gold.

What's Too High?
It is almost impossible to state what the ratio "should" be. We give a brief history of it on our Gold Silver Ratio page, and we have created other pages with recent historical prices.
A good guide is probably to take the average over the most recent few years, as it is probably the best guide to where it "should" be in the next few years.
As we wrote this page (28th October 2008), the ratio was just over 83, which is a near record high since 1993. The mean average ratio since 1970 has been around 54.
Divide 83 by 54 = 1.857, which means silver is about 54% too low, or gold is about 35% too high.

Accounting for VAT
We do have some UK customers with VAT registered businesses, and they may to able to reclaim the VAT, but for most private investors, VAT on silver bars or coins remains in inconvenient and iniquitous tax, which is why we do not normally recommend it, however sometimes, such as now, even losing the VAT, silver looks a better bet than gold.
Taking the current ratio of 83:1, and allowing for VAT (Gold/[Silver*1.175]), gives an after VAT ratio of over 70:1, which is still well above the recent average levels of about 54:1, and making silver theoretically still about 30% too cheap compared with gold.

Putting Our Money Where Our Mouth Is
For the dual benefit of our customers and ourselves alike, in the past few weeks, we have invested some of our spare capital into silver rather than gold, indeed we have used this to partially hedge our gold position, as it is difficult to source physical stocks of gold in the new and secondary markets.
As we wrote this, we had orders for over 1 tonne of silver bars, and over 3 tonnes of silver coins, ordered, paid for, and in production or awaiting shipment. We also have about 1/5th tonne of gold on order.

Supply Problems
In case any of our readers have not noticed the global banking, credit, liquidity, and mortgage crises, these have influenced a large number of people worldwide, and we are seeing almost unprecedented demand for physical gold and silver, in the form, of both coins and bars.
Most of the world's biggest gold and silver bullion coin producing mints are fully stretched trying to keep up with demand. The Royal Canadian, US, South African Austrian, Mexican, Chinese, and Perth (Australian) mints are quoting long delivery periods, up to about two months, or have stopped accepting or restricted new orders. Our own British Royal Mint does not generally have competitive prices for its bullion coins, and seems to prefer to market "added value" products.
Commonly available gold bullion coins such as sovereigns, Krugerrands, maples, eagles, and Philharmonicas are almost impossible to source new.
Amongst one ounce silver coins, the most popular are normally Canadian silver maples, American silver eagles, and Austrian Philharmonicas, in that order, because that also happens to be the ascending order by ex-works premium.

Best Buys
We currently have good stocks, and forward orders for, one ounce Australian silver coins in three designs. The Perth Mint's seignorage charge (manufacturing premium) is higher for these than for the other three main one ounce silver bullion coins, but they only work out at about £1 each more than the others, so they are currently a worthwhile buy.
Kilo silver bars are generally one of the cheapest ways to buy silver bullion, but one kilo silver coins are not much more expensive, and there are some advantages when it comes to reselling them (they can be bought and sold on VAT margin scheme), so in our opinion are probably a better buy than kilo silver bars.
The intermediate sizes of silver coins, two ounce, ten ounce, five ounce, and half kilo enjoy intermediate premium rates, better (less) than one ounce coins, but not as good as kilo coins.
As our stocks change on a daily basis, our sales staff should be able to tell you what coins we have in stock, and what are expected for early delivery.

What Premium on Silver Coins and Bars
We are often asked what the percentage premium is one silver coins and bars. We do not normally calculate this figure, because our cost prices are based on silver, plus an amount in US dollars, plus shipping and insurance costs. Our selling prices add a percentage to this, then we have to add VAT (for EU customers). Because of this, the actual percentage premium fluctuates. An investor can easily calculate it by taking our selling price, divided by the spot silver price. This is easy for one ounce coins. For kilo coins, first divide the price by 32.15, to find a price per ounce.

Volatility
Anybody who studies the movement of gold and silver prices over the past few decades, or centuries, will find that the price of silver tends to fluctuate more than the price of gold. This is known as volatility. When silver prices go down, they tend to go down by more in percentage terms than gold. Conversely when silver prices rise, they tend to rise by more than the gold price, again in percentage terms. For this reason, many investors are "silver bugs", and enjoy dipping into and out of the silver market. Many of our customers make good short to medium term profits from doing this.

Gold Silver Price Ratio
When the first coins were made over 2,500 years ago in ancient Greece, the ratio of gold to silver was generally between 10:1 and 13.5:1, depending on the relative proximity of gold or silver mines. In the 1930's and 1940's the ration reached 90:1 or higher, and in 1991 it peaked at about 98:1, although we have seen one source which claims over 100:1 peak. Other sources state that the gold silver ratio is no longer relevant in today's markets. We believe it is a worthwhile measure, but would stress that it is difficult if not impossible to state what the ratio "should" be.
