How are Silver and Gold Premiums Calculated?

The price paid for each ounce of bullion is composed of the metal’s spot price and the bullion premium.

Here’s the price composition of some common rounds:

•Silver Eagle: 80% spot price / 20% bullion premium

•Silver Canadian Maple Leaf: 84% spot price / 16% bullion premium

•Gold Eagle: 96% spot price / 4% bullion premium

Difference Between Spot Prices and Bullion Premiums

How are these bullion premiums determined? How can bullion buyers take advantage of the lowest possible premiums?

Spot Price: The current price per ounce exchanged on global commodity markets.

Bullion Premium: The additional price charged for a bullion product over its current spot price.

The calculation for bullion premiums depends on five key factors:

  1. •The current bullion market supply and demand factors.
  2. •Local, national, and global economic conditions.
  3. •The volume of bullion offered or bid upon.
  4. •The type of bullion products being sold.
  5. •The bullion seller’s objectives.

Bullion Supply and Demand

The total amount of supply and demand of bullion is a major influence on bullion product premiums.

Bullion dealers are businesses, and they are actively trying to balance product inventory and profitability. Too much inventory means high costs. Too little inventory means angry customers. Fluctuations in the gold and silver markets affect bullion market supply, and this impacts premium prices.

For example, in the Western hemisphere during the summer, calmer price patterns mean the bullion supply tends to increase. Sellers mark down their prices to attract market share.

During other months, silver and gold prices tend to have more volatility. This leads to increased buying and selling, and bullion sellers react accordingly. Some may mark up prices to prevent running out of inventory, or to capture profits.

Economic Conditions

Depending on their size and significance, market events can affect bullion premiums local to global stages.


  • •In a small town with only one brick and mortar coin shop, the dealer may boost their premiums to guard against running out of inventory.
  • •In a country like Venezuela, where the local currency is losing value at an extreme rate, locals may opt to buy bullion to preserve their wealth. This means higher premiums.
  • •At a global level, in the event of a large crisis (similar to the 2008 Financial Crisis), it is likely premiums would increase significantly as demand spikes and options diminish.Volumes Being Sold

Every seller incurs costs on each transaction such as time, overhead, or payment processing costs. For a seller, a single transaction for 1 oz of gold may have similar transaction costs as a 1000 oz transaction.

Therefore, transactions with higher volumes of bullion have their costs spread out. As a result, premiums tend to be higher on small volume purchases, and lower per oz on high volume buys.

Form of Bullion for Sale

As a general rule, the larger the piece of bullion is, the less the premium costs are per oz.

It costs a mint far less to make one 100 oz silver bar, vs. 100 rounds of 1 oz each.

There is also typically a significant difference in premiums between government and private mints.

For example the most popular bullion coins in the world are American Silver and Gold Eagle coins. The U.S. Mint charges a minimum of $2 oz over spot for each Silver Eagle coin and +3% over spot for each Gold Eagle coin they strike and sell to the world’s bullion dealer network.

A private company like Sunshine Minting will sell their silver rounds and bars in bulk for less than ½ the premium most government mints will sell their products for.

Bullion Seller’s Objectives

Whether the seller is a large bullion dealer or a private individual, they will almost always want to yield the highest ask price they can get for the bullion they are selling.

That said, just because one wants to receive a large premium on the bullion they are selling, that doesn’t necessarily mean the market’s demand or willing buyers will comply.

Dealers must consider these factors when setting premiums:

  • •Market share objectives
  • •Competitor strategies
  • •Price equilibrium strategy

If a dealer sets its price too high, buyers will likely choose to go to a lower priced competitor.

If a dealer sets their price too low, they could end up selling out of inventory without garnering enough profit margin to pay for the company’s overhead costs.

Dealers and sellers are both typically trying to find the price equilibrium “sweet spot” where the time required to complete a sale is minimized and the seller’s profit is maximized.

This is more difficult than it sounds, as there can be thousands of factors at play when establishing the best possible premium to charge in line with one’s overall objectives.

Price Composition for Bullion Products

When bullion markets are experiencing normal demand, about 80-95% of silver bullion’s price discovery is comprised of the current spot price.

For gold, spot prices approximately comprise of 95-98% of gold bullion’s overall price discovery.

Delivery — Delivery generally refers to the change of ownership or control of a commodity under specific terms and procedures established by the Exchange upon which the contract is traded. Typically, except for energy, the commodity must be placed in an approved warehouse, depository, or other storage facility, and be inspected by approved personnel, after which the facility issues a warehouse receipt, shipping certificate, demand certificate, or due bill, which becomes a transferable delivery instrument.

A soft, shiny, yellow, heavy, malleable, ductile (trivalent and univalent) transition metal, gold does not react with most chemicals but is attacked by chlorine, fluorine and aqua regia. The metal occurs as nuggets or grains in rocks and in alluvial deposits and is one of the coinage metals.

For example: the sale of futures contracts in anticipation of future sales of cash commodities as a protection against possible price declines, or the purchase of futures contracts in anticipation of future purchases of cash commodities as a protection against the possibility of increasing costs.



Intrinsic Value — The actual value of the precious metals contained within a bullion bar or coin.

Inverted Market — A futures market is said to be inverted when distant contract months are selling at a discount to nearby contract months; also known as backwardation.

Platinum is used in jewelry, laboratory equipment, electrical contacts, dentistry, and automobile emissions control devices.

Premium — The market value of a coin less the intrinsic value of its metal content. A coin that contains $6.00 of silver (intrinsic value) and sells for $7.50 (market value) has a $1.50 premium.

Settlement Price — The price established by the Exchange settlement committee at the close of each trading session as the official price to be used by the clearinghouse in determining net gains or losses, margin requirements, and the next day’s price limits. The term “settlement price” is often used as an approximate equivalent to the term “closing price.” The close in futures trading refers to a brief period at the end of the day, during which transactions frequently take place quickly and at a range of prices immediately before the bell. Therefore, there frequently is no single closing price, but a range of prices. In months with significant activity, the settlement price is derived by calculating the weighted average of the prices at which trades were conducted during that period.

Silver — A chemical element in the periodic table that has the symbol Ag (from the traditional abbreviation for the Latin Argentum) and atomic number 47. A soft white lustrous transition metal, silver has the highest electrical and thermal conductivity of any metal and occurs in minerals and in free form. This metal is used in coins, jewelry, tableware, and photography.

1 ounce Troy = 480 grains = 31.1035 grams = 1.09711 avoirdupois ounces


Unallocated Metal — Refers to the accounting assignment, or reporting of, precious metals balances denominated in ounces to a particular account, also known as a statement account. Unallocated holdings are sometimes referred to as “pooled holdings” because they may comprise a mix of various products held at various custodians. The mix of products (in ounces) equals the unallocated balance (in ounces). In an unallocated account, specific bars or coins are not assigned to any particular customer; customers own a proportionate interest in the bulk holdings.
