Pennyweight (Jewelers' Traditional Unit)

Introduction : The pennyweight is a small unit from the troy weight system, which is used for precious metals. One pennyweight equals 24 grains, or about 1.56 grams. The symbol 'dwt' comes from 'denarius weight,' a reference to an old Roman coin. Jewelers in the past used pennyweights for weighing gold, silver, and small gemstones. Today, the pennyweight is less common than grams or troy ounces, but it still appears in some jewelry stores and pawn shops. For people who buy and sell scrap gold, the pennyweight offers a handy middle size between the tiny grain and the larger troy ounce.

History & Origin : The pennyweight has a name that tells its story. In medieval England, a silver penny coin was supposed to weigh exactly 24 grains. That weight became known as a pennyweight. The pennyweight became part of the troy weight system, which was used for coins, precious metals, and medicines. There were 20 pennyweights in a troy ounce and 240 pennyweights in a troy pound. This system lasted for centuries in England and America. The United States Mint used troy weights for coin making until 1828. As the metric system spread, the pennyweight faded from official use. However, the name lives on in the symbol 'dwt,' which stands for 'denarius weight' from the Roman coin that started it all. The pennyweight is a small piece of history that still weighs precious metals today.

Current Use : The pennyweight is most commonly found in jewelry stores and pawn shops that buy used gold. A jeweler might say a gold ring weighs 5 pennyweights instead of 7.8 grams. Pawn shops sometimes post their gold buying prices per pennyweight. Gold scrap buyers, who melt down old jewelry for the metal, often use pennyweights in their calculations. Some jewelry makers, especially older ones, still think in pennyweights when designing pieces. The unit is also used in some coin collecting circles for very old coins. Online gold trading forums discuss prices in dollars per pennyweight. While grams are taking over, the pennyweight refuses to disappear completely. For people in the gold trade, knowing pennyweights is like knowing a secret language of value.

Tael (Traditional Chinese Weight)

Introduction : The tael is a traditional Asian weight unit that is smaller than the catty. One catty equals 16 taels in the traditional system, so one tael is about 37.8 grams in Hong Kong. In mainland China, where the catty is 500 grams, one tael is 31.25 grams. The tael has been used for thousands of years to weigh precious things like silver, gold, and herbal medicines. In ancient China, people paid with silver taels. Today, the tael is still used for gold trading, traditional medicine, and in some markets. The tael connects modern Asia to its ancient past as a center of trade and commerce.

History & Origin : The tael has a very long history that goes back to the earliest Chinese dynasties. It was originally a weight for measuring silver, which was used as money. People carried silver taels in their pockets and paid for goods by cutting off pieces of silver and weighing them. The name 'tael' came from the Malay word 'tahil' through Portuguese traders. Different parts of China had different taels, which made trade complicated. There was the Shanghai tael, the Canton tael, and the customs tael. Each was slightly different. In 1933, China abolished the tael as money and switched to a national currency. However, the tael as a weight unit never died. Hong Kong legally defines the tael as 37.8 grams for precious metals. Gold shops in Hong Kong still use the tael every day. The tael is a survivor from the age of silver money.

Current Use : The tael is most actively used today in gold and silver trading in Hong Kong, Singapore, and other Asian financial centers. When you walk into a gold shop in Hong Kong's famous Wing On Street, prices are listed per tael. Gold necklaces, bracelets, and rings are weighed in taels. Traditional Chinese medicine shops measure rare herbs and medicines in taels. Some recipes for herbal teas and soups call for a few taels of dried ingredients. In Taiwan and mainland China, older generations still think in taels at wet markets, though younger people prefer grams. Jewelry for weddings often includes gold pieces measured in taels. The tael is also used in some antique markets for weighing old silver coins and bars. For anyone buying gold in Hong Kong, knowing the tael is essential.
