How to Decipher a Coin


A coin is a small piece of metal that people use as money. It can be made from gold, silver, copper, brass, nickel, or even tin. Some coins have a design on them, while others have a numeric value printed on them. Some coins have a reeded edge, while others are rounded. A reeded edge means that the coin was made by hand, while a rounded coin was minted using machines. A coin can also be used to pay for food, drinks, or tickets at a concert or event.

In the past, coins were mostly made of precious metals such as gold and silver. However, these were difficult to use as money due to their high cost and difficulty in transporting them. To make it easier to trade and exchange goods, the people of Lydia in Asia Minor shaped electrum, a natural alloy of gold and silver, into bean-shaped lumps of fixed weight and purity and stamped them with official symbols. These were the earliest known coins.

Later, the Roman Empire began to produce coins of great artistic beauty, establishing the standard for fine coinage in Europe. These early coins helped facilitate commerce and trade, and were widely recognized throughout the Roman Empire and beyond. Today, most coins are made of metals such as cupro-nickel (copper 75%, nickel 5% and zinc 20%, with silver in color), aluminium-bronze (90% aluminum and 10% bronze), or simple plated steel.

The first step in deciphering a coin is to load the 3d model for the best view of the markings. Then find the numeric denomination — how much the coin is worth — by looking along the edge for a single number followed by r or s. The side of the coin carrying this information is called the obverse, while the opposite side is usually the reverse. However, some coins, such as the British 20p coin, have a different obverse and reverse sides, while others, such as the Mexican peso, have a reversible obverse and reverse.

Once you’ve found the coin’s value, look for other markings that indicate how the coin was produced. For example, find the mint mark by looking for a symbol next to the numeric denomination. These are usually either an m or a n, but can also be c, e, or s. If you can’t find the mint mark, refer to this chart to find out where the coin was made.

There are several ways to earn Coin, including walking into stores that the in-app map highlights, answering rewarded surveys, and joining in-app sweepstakes. The Coin app also allows users to “claim” mining regions and compete with other app users to mine the most COIN. You’ll need to keep your phone on and running the app to earn these passive rewards, which can take a toll on battery life. This review will cover the benefits and drawbacks of Coin so you can decide whether it’s right for you.
