The process of making Minted Bars and Coins (Gold Bullions or Silver Bullions) begins by melting some fine metal into a continuos melting furnace which makes it into a thick strip of pure gold or silver.
The strip is then rolled and annealed and cleaned in different steps, to reach the desired thickness.
A subsequent rolling is required, using a finishing rolling mill, to achieve the final accuracy in terms of thickness and finishing.
The strip is then ready to be cut into blanks using a press and subsequently finished with the customized logos and information impressed by minting using a press.
The most common sizes of the minted bars and coins are the following:
- 1, 2, 5, 10, 20, 50 g (grams)
- 1 tola and 2, 3, 4, 5 tolas
- 1 tael and 5 taels
- 1 baht
- 1, 10 chi
- 1/10, 1/4, 1/2 and 1 oz (ounces troy)
The packaging is the last step of the process and it’s done to protect the bars from scretches and to guarantee security and authenticity of the final product.
