Genuine gold coins and gold bars minted primarily for investment use get their value mainly based on the gold they contain. The sale of gold coins and gold bars intended for investment is VAT-free. Unlike gold bars, gold coins, like all coins, also have value in the collector's mind.
It is good to note that there are also gold coins that do not meet the hallmarks of tax-free investment gold, and such "gold coins" are not well suited for investment use due to the VAT applied to them. The gold coins and bars sold by Gemtrade are all genuine and approved as VAT-free investment products.
In addition to the market price of gold, the selling price always includes an extra "making" price, i.e. the manufacturing and distribution costs of coins and ingots, as well as the costs of intermediaries. In our sales price, these extras are minimized, the price is directly the importer's price, which means you always get the best possible value for your investment.
