Investment gold is exempt from VAT, making both gold coins and bars available at a low premium. Gold coins are more popular among individuals due to their increased liquidity, with the 1 troy ounce size being the most widely utilized globally. The most favored gold coins include the Maple Leaf and the Krugerrand.
Gold bars are often preferred for larger purchases, with 50-gram and 100-gram bars being the most frequently selected. It's important to consider that prices per gram become more appealing with larger gold bars, although heavier bars offer less flexibility.
 

• Gold coins containing 1 troy ounce of fine gold are the most common
• Gold bars of 50 grams and 100 grams are the most popular for larger order quantities

Silver is mainly regarded as an industrial commodity, which subjects it to a 21% VAT. Silver coins are traded under the margin scheme. For individuals, silver coins are typically the optimal choice. Pre-owned coins, especially those from previous years, offer the most cost-effective option and present the smallest gap between buying and selling. Common coins are minted in 1 troy ounce of pure silver, including the Maple Leaf, Philharmonic, and Britannia.
If you're looking to invest larger sums, consider VAT-exempt silver: industrial silver bars held in a customs warehouse in Switzerland. While this is the cheapest method to invest in silver, you won’t have the physical silver in your possession.
 

• Silver coins are the preferred choice for individuals
