Physical precious metals are tangible assets that can be identified by metal type, weight, purity and form. In the context of bullion, the focus is primarily on the amount and quality of the underlying precious metal rather than on decorative design or collectible rarity. For Alloy Academy, this distinction is important because the educational framework begins with the metal itself before moving into pricing, custody, settlement and ownership.
The four core precious metals
Gold, silver, platinum and palladium all belong to the precious-metals market, but they do not serve identical roles.
Gold is widely recognized as a monetary and investment metal as well as a material used in jewellery and selected industrial applications. Silver also has a long history as a precious metal, but industrial demand is a significant part of its market. Platinum and palladium are both platinum-group metals with important industrial uses and more specialized physical markets.
These differences matter because physical availability, product formats and market demand can vary from one metal to another. A buyer looking at a gold bar and a buyer looking at a platinum bar may both be purchasing physical bullion, but the supply conditions and product choices can be very different.
What qualifies as physical bullion?
Bullion generally refers to precious metal valued primarily for its metal content. It is commonly produced in standardized forms such as bars and coins, with specifications that identify the metal, weight and purity.
A bullion product should therefore be read as a specification. A description such as a 1 kg cast gold bar at 999.9 fineness communicates three essential facts: the product is gold, it weighs one kilogram, and its stated purity is 999.9 parts per thousand.
The same logic applies to other products, such as a 100 oz silver bar or a 1 oz platinum bar. The form may change, but the basic questions remain the same: what metal is present, how much does the product weigh, and what is its purity?
Physical metal is more than a price
A common mistake is to think of precious metals only as quoted prices on a screen. Physical ownership adds additional layers.
The owner must know what product is being held, how it is identified, where it is stored, how title is recorded and how the metal can eventually be delivered or sold. Product form also influences handling. A large bar is not operationally identical to a small coin even when both contain the same type of metal.
This is why Alloy Academy separates the idea of a metal price from the idea of a physical holding.
Bullion form matters
Bars and coins can both provide exposure to physical precious metal, but they are manufactured and handled differently. Bars can be cast or minted, while coins are normally produced to defined specifications and may carry higher fabrication or distribution costs.
Larger products can concentrate more metal into fewer physical units. Smaller products may offer greater divisibility. Neither form is automatically better in every situation; the relevant consideration is how the product fits the intended holding, storage and eventual transfer.
A foundation for the rest of the course
Before studying premiums, settlement or custody, it is necessary to understand the physical object at the center of the transaction.
Every bullion holding can be examined through four basic questions: which metal is it, what form does it take, how much does it weigh, and what is its fineness?
Once those elements are clear, later topics such as pricing, allocation, vault documentation and buy-back become much easier to understand.
