Main Facts Deciding the Coin's Price
The coin price guide depends on some main easy parts, always working together, creating the final amount of money a buyer wants to pay for it. These parts include the coin's physical look, its total number in the world, the metal used for making it, and the interest from people collecting coins.
If one of these parts is very high, for example, the coin is in perfect condition, then its price will be high, even if it is made from common metal.
How Good It Is Kept
The coin's look is the most important part for its price, meaning how much the coin is used, whether it has broken places, and how close it looks to a new coin from the mint machine. The less signs of use and time on the coin, the higher its final selling price will be.
Simple Look Levels
To truly tell how good a coin looks, people use special words, having numbers in special systems, but we will use their simple meanings now.
Uncirculated never went into normal use, meaning it was not in pockets or used for buying things. It has no signs of use or rubbing on its highest points, keeping its first bright shine from the mint, making its price much higher. This is the highest level of look, making coins in this state always cost much more money.
Very Fine coin was in use, but only for a short time, showing small wear only when you look very closely at it. All big parts of the picture and words stay clear and easy to read, with only small picture parts being a little gone, staying a good look for most old coins.
Good coin was in use for a long time, showing many strong signs of use now. A big part of the high picture is gone, making some small picture parts not easy to see. The words and the year might be visible, but not always very clear, meaning these coins have a low price, often close to the metal's price.
Poor coin was used so much that most of the pictures and words are gone, making the year and country not visible. Such coins have value only if they are very rare by themselves, no matter how bad they look, for example, if only a few coins are still left.
Damage Making the Price Lower
Any change to the coin after the mint made it always makes its price lower, except for the natural change in color, called patina, when it looks nice.
Scratches are any lines or marks on the surface, coming from hitting other things or coins. Deep scratches, especially those going across a face or picture, make the coin's price much lower.
Trying to remove dirt or color with strong liquids or tools like brushes leaves very small scratches on the coin, destroying its natural look and the patina, immediately making the coin worth less for serious collectors. Good cleaning is almost impossible, making most collectors strongly dislike it.
If someone made a hole in the coin to wear it as jewelry, this moves the coin into the category of broken coins. Having a hole makes its price drop to the metal's price or lower, except in very few rare cases.
Breaking the coin's side, coming from dropping or hitting something, also makes the price go down.
The Part of Patina and Toning
Patina is the natural color or surface change, appearing on the coin over a long time, happening because the metal reacts with the air, becoming a nice layer.
If the patina looks the same everywhere, having nice colors, it can make the coin's price higher, because it protects the metal and shows the coin was not cleaned, making it valuable as a sign of age.
Trying to make patina fast with chemicals looks not real, being quickly seen by good collectors, making the coin's price drop quickly.
Coin Rarity
Rarity tells how often you can find the coin in the market, meaning the fewer coins of this kind are left, the higher the buyer competition, making the price go up.
Minting Number
If the mint initially issued only a small number of coins, for example, less than 10,000 pieces — this becomes the first reason for its high price.
Number of Coins Still Left
The first minting number is not the complete story, with the number of coins surviving until today being more important.
A lot of old coins were taken out of use, being melted into new metal by the government. If the government took away and melted 90% of the coins, the remaining 10% would become very rare, even if the first minting was big.
Coins could be lost, sink in water, or be broken so much that collectors do not want them. The real rarity is found by counting the coins that are in collections and ready to be sold.
Mints and Small Differences
Some mints operated for a very short time or produced fewer coins — for example, an 1890 coin made in Denver may cost much more than a similar coin made in Philadelphia, just because Denver produced 50 times fewer coins.
The Price of the Material
For coins made of expensive metals such as gold or silver, the price can never be less than the price of the metal inside.
Basic Metal Price
Each coin has a specific weight and a specific purity of the metal, for example, holding one ounce of clean gold.
Most coins are not completely clean metal, with silver coins often having 90% silver and 10% copper for strength, meaning the metal price is only for the clean metal part.
Extra Price Above the Metal
The difference between the price the coin sells for and the price of the metal inside is called the premium.
Coins people buy mainly for the metal, like modern "American Eagle" coins, have a small extra price maybe 10-20% more than the metal price because there are many of them.
Market Interest
Collection Sets
Coins being part of a well-known, liked, and full set always have higher demand.
Collectors gathering the whole set for example, all coins made in a certain country from 1900 to 1950 want to pay more for the last coin they need, helping them finish their collection. The price of a coin that finishes a set is often higher than its normal price.
The more famous a coin set is in the collector world, the more people join in, making the demand higher.
Authenticity
The coin must be real, meaning if people think the coin is fake or a copy, its price is zero.
The price of a coin checked and placed in a special plastic box by a known rating company is always higher. This box gives buyers trust that the coin is real and its look is correct, making demand go up.
The more expensive and rare the coin is, the more people try to make fakes, meaning collectors pay more to avoid this problem, buying coins with official papers.
Provenance
The story of the coin's owners can add a lot of money to its price, even if the coin is not the most rare one.
Being Part of Famous Collections
If an item was sold at a large, well-known auction, indicating its authenticity — it also increases its price. Buyers pay extra for a reliable ownership history and the good name of past owners.
Papers
Having old notes of buying or selling, or old photos showing the coin, can increase its worth. Papers show the coin has been in collections for a long time, making its history known.
Money and Outside Facts
The general money situation and other outside events also change the coin prices.
Price Rise
When money becomes less strong for buying things, people often start buying gold, silver, and other items, including rare coins, trying to keep their savings safe. This makes the demand for coins higher, especially for metal coins, making their price increase.
During money problems, the demand for very expensive, rare coins might go down, because people need to focus on more important spending. But the demand for gold and silver coins, as a way to keep money safe, can stay high.
Buyer Ability
The price of a coin, especially a very rare one, depends much on the number of rich people wanting to collect. If more very rich people appear in the world, wanting to own rare items, this pushes the prices for the best coins higher.
