What is a cast gold bar

A cast gold bar is made by pouring molten refined gold into a mould and allowing it to cool. The result is a bar with an irregular surface texture and a more industrial appearance compared to a polished minted bar. Cast bars typically carry minimal packaging and no elaborate assay card.

What cast bars lack in presentation they make up for in value. Because the production process is simpler and faster than minting, cast bars carry the lowest premiums of any gold product available in Australia. For investors who want maximum gold for minimum premium, cast bars are the logical choice. If presentation matters to you, gold minted bars are available from the same dealers at a slightly higher cost.

Why cast gold bars carry lower premiums

The premium on a gold product reflects the cost to produce it. Minting requires precision equipment, quality control, and branded packaging. Casting requires a furnace, a mould, and basic handling. The production cost difference is passed on to buyers as a lower premium.

A typical 100g cast bar from a reputable Australian refiner carries a premium of 1 to 3 percent over spot, compared to 3 to 6 percent for a minted bar of equivalent weight. On a A$10,000 purchase, that difference is A$200 to A$300. Over multiple purchases, choosing cast over minted can represent a meaningful saving that compounds as gold appreciates.

Cast bars vs minted bars vs coins

Cast bars deliver the most gold per dollar spent. They are the right choice for investors who are building a position and prioritising value over presentation. The trade-off is that cast bars can be slightly harder to resell to private buyers who prefer the look of a minted bar or coin, and international dealers may want assay verification for brands they do not recognise.

For buyers who want easy liquidity on smaller amounts, gold coins are more practical. For buyers who want a presentable product with assay certification, gold minted bars are the middle ground. If you are still deciding, the how to buy gold guide has a detailed comparison of all three product types.

Capital gains tax on cast gold bars in Australia

When you sell a gold bar in Australia, any profit is subject to capital gains tax. If you have held the bar for more than 12 months, you are eligible for the 50 percent CGT discount, meaning you pay tax on only half the gain. Gold bars held inside a self-managed super fund may attract even lower effective tax rates.

The gold CGT guide explains how CGT applies to physical gold, including the proposed 2027 changes that could affect large holders. If you are buying gold through an SMSF, the SMSF gold guide covers the specific rules and best practices.
