What 4 countries still use coins with holes in them?
The four countries that still use coins with holes in them are Japan, South Korea, the Philippines, and Indonesia. These coins are known as "holey coins" and are typically used for denominations of 1 yen, 5 won, 1 piso, and 50 rupiah respectively. The holes in these coins serve both functional and symbolic purposes, such as making it easier to string them together or representing the country's cultural heritage.
Does a 1950 coin have a hole in the middle?
The country of origin and the denomination of the coin would be a big help. Holes in the centre of coins is no longer as widespread a practice as it once was, although some countries continue to do so as a tradition.
Why are coins different sizes?
Originally coins were different sizes because their values were determined by how much metal they contained. For example, a US dime had roughly 10 cents worth of silver in it, a British sovereign had roughly a pound's worth of gold, etc. People could associate a coin's value with its size, making it easy to tell them apart. Even though circulating coins today don't have any precious metals in them, different sizes still help people to easily distinguish one coin from another without looking at its design or denomination. Having different sizes also facilitates the use of mechanical sorting equipment. Mixed coins are passed through a kind of filter with holes of increasing sizes. The smallest coins drop through the smallest holes first, the next size coins drop through the second set of holes, and so on, and are collected in bins.
How do you make coins moldy?
You can put coins in an mouldy wrapping and some of the mould spores will rub off onto the coins. This will make the coins LOOK mouldy but, being metallic, they will not actually be mouldy.
Are coins an element?
No, coins are not an element. Some coins may be made of nearly pure gold, silver, aluminum, or other metal elements, but most present-day coins are made of various metal alloys, often with different composition on the inside than on the outside.
