For 4000 years, precious metals (gold and silver) in the form of coins and bars have served as a means of exchange and payment. In all that time, they have not suffered any loss of material value or significance. Today, gold bars of fine gold serve as a financial investment, which can be easily traded. Above all, they are considered a crisis-proof store of value. Modern gold bars are stamped with the characteristics of weight in grams, fineness and the manufacturer. However, a nominal value is not mentioned, as it is common for gold coins and silver coins.
The price of tradable gold bars is based on the price of gold. The production costs of bars are lower than those of coins, which is why fine gold bars are usually cheaper compared to bullion coins. However, lower prices are paid for bars from manufacturers without a good delivery certificate.
From movies we know mainly the Good-Delivery standard bars with a weight of 400oz, which is just under 12.5kg. These bars are used mainly by major banks and states. In contrast, investment gold bars in sizes ranging from 1g to 1kg are common as easily tradable LBMA bars. While smaller "mint" bars are minted similar to gold coins, larger bars - usually 250g and above - are produced as cast bars.
Reputable manufacturers whose gold bars are bought by almost all banks and precious metal dealers worldwide at reasonable prices can be found on the so-called "Good Delivery" list of the London Bullion Market Association (LBMA). These manufacturers are regularly audited independently and are repurchased by all banks worldwide.
