FAQs about How Are Gold Coins Made

How are gold coins made?

Gold coins are made through a process called minting. Here is a step-by-step guide:

1. Designing the coin: Technical artists create designs and a sculptor creates a clay model.
2. Creating the mould: The clay model is used to make a plaster mould, which is then coated with rubber to create an epoxy resin mould.
3. Transfer engraving: The epoxy resin mould is mounted onto a transfer-engraver machine, which reduces the design to coin size and transfers it onto a steel blank known as a ‘master hub’.
4. Creating the master die: Heat treated metal is smoothed into a measured blank die, and the master hub is pressed into this die to create the ‘master die’.
5. Creating working dies: The master die is used to create working hubs, which go through the same process to create the working dies used for the striking process.
6. Striking the coin: Gold or silver is melted and poured into cylindrical billets, which are then made into thin strips and cut into smaller lengths. These strips are punched into discs called ‘blanks’ using a blanking press. Each blank is weighed, washed, and polished. The blanks are then placed in a coining press, where impressions are made on both sides of the coin.

What materials are used in the production of gold coins?

Gold coins are typically made from 22ct gold, which consists of 91.67 percent pure gold. The remaining 8.33 percent is made up of metals like silver, copper, zinc, nickel, and other alloys. These additional metals are added to make the coin harder and more durable.

Why are gold coins made with 22ct gold instead of 24ct gold?

Gold coins are made with 22ct gold instead of 24ct gold because coins need to be harder to withstand use as a means of exchange. 24-carat gold, which is 99.95 percent pure, is too soft and less dense, making it unsuitable for use in coins. Adding other metals to the gold increases its hardness, making it more suitable for coins.

How can I determine if a gold coin is genuine?

Biting a gold coin, as depicted in movies and TV series, can determine its authenticity. Gold is harder than materials like lead, so biting a gold coin can reveal if it is genuine or merely plated. Additionally, gold is a good heatsink and does not heat up quickly. Putting a gold coin in the mouth can help detect temperature variances, which can further indicate its authenticity.

What is the significance of the gold purity rating in gold coins?

The carat rating is used to measure the purity of gold. 24-carat gold represents pure gold, which is at least 99.95 percent pure and contains only minute traces of other metals. A lower carat rating indicates a lower purity level and the presence of more impurities in the gold.

Why should I consider investing in gold coins?

Investing in gold coins can be a good first step in gold ownership as it provides not only the opportunity for good returns on the gold itself but also insight into a trading world that is fading in today’s commercial world. Gold coins can serve as a valuable investment and a store of wealth.
