Credit Suisse bars are among the most popular in the world. Credit Suisse actually creates its gold bars in the factories of Valcambi SA, a well-known global manufacturer of gold bars, a Swiss company headquartered in Balerna.
In the 1960s and 1980s, Credit Suisse owned this company, but much has changed in the past 40 years. However, Valcambi and Credit Suisse continue to collaborate on the production of cast and measured gold bars. In the United States, Credit Suisse Gold Bars are accredited by IRAs (US retirement programs).

Johnson Matthey is a British company with a long history in the production of precious metals. They became the official manufacturer of silver coins in the UK in 1946 and have since remained at the forefront of popularity. Their gold bars come in a wide variety of sizes, designs, shapes, and levels of sophistication.
Instead of paying for the expensive minting process, as many manufacturers do, Johnson Matthey produces bars with a simplified design. This reduces their cost for investors. Just like Credit Suisse gold bars, Johnson Matthey is known and trusted all over the world.

The Perth Mint is the oldest mint in Australia. Its construction began in 1896. About 60% of Australian gold is processed in Perth. The Perth Mint's bullion bars range in weight from 1 gram to 1,000 ounces.

The "Gold Minted Bars" series offers weight denominations of 5, 10, and 20 grams, as well as 1 ounce and 10 ounces. These bars feature a jumping kangaroo design. The special packaging with tamper-evident features makes the Perth bars more attractive and expensive.

The Swiss company Valcambi supplies the market with gold bars with a unique design. Stamped rectangles weighing from 5 to 100 grams look like a chocolate bar. The lines of the break are perforated. This makes it easy to break off small pieces from the general bar, carry them in your wallet and use them as payment. The production of bars with this design started in 2011. There are many jokes in the world that such bars will be useful during the apocalypse, to use them instead of a credit card.

Also the Swiss company Valcambi produces a 999.9 grade combo-bars in the form of a five-pointed star weighing 5 grams. Such a combo-bar can be divided into 5 bars weighing 1 gram each.
