What Are the Different Types of Gold You Can Sell?

There are lots of variations of gold items that you can sell to professional gold buyers who are looking to buy jewelry. These items may include gold coins, gold bars, gold jewelry, and even dental gold. When it comes to selling your jewelry, it's important to find the best place to sell gold. Professional gold buyers can offer you competitive prices for your gold, and they can also provide you with helpful tips and insights about the gold-selling process. When it comes to gold jewelry, there are various styles and types that you can sell. Some popular styles include classic gold chains, elegant gold bracelets, and stylish gold rings.

Additionally, there are different types of gold that you can sell, such as yellow gold, white gold, and rose gold. Yellow gold is the most common gold and is made by mixing gold with copper and silver. White gold is made by mixing gold with nickel, palladium, or platinum, and it has a silvery appearance. Rose gold, on the other hand, is made by mixing gold with copper, which gives it a pinkish hue. In addition to the different types and styles of gold jewelry, you can also sell other gold items such as gold coins and gold bars. 

Gold coins are collectible items that can hold significant value, and gold bars are often used as a form of investment. No matter what type of gold item you must sell, it's important to find a reputable professional gold buyer who can provide you with the best possible price for your gold. Knowing where to sell gold is just as important as knowing what you can sell, getting the best possible price for your jewelry is essential as there are many locations that will offer less value.

What is a "Raw" Coin?

A "raw" coin is a term used in numismatics to describe a coin that has not been certified and encapsulated by a third-party grading service like Numismatic Guaranty Company (NGC) or Professional Coin Grading Service (PCGS). Raw coins, also referred to as ungraded coins, are sold in their natural state, as issued by the mint. They will not arrive with any numerical or adjectival grade affixed to them and are usually packaged in a cap or a flip versus being sonically sealed in a protective slab like a graded coin would be.

What’s the Difference Between a Scarce Coin and a Rare Coin?

Rare vs. Scarce Coins

Rare coins are the result of a low original mintage or low surviving population (meaning they were heavily used in circulation or melted down over time), , giving them significant collector appeal compared to common coins. Their “rarity” is not likely to change. On the other hand, scarce coins are coins that are hard to find at a particular moment, possibly due to temporary market conditions like low supply or high demand. While scarce coins are not typically encountered in public circulation, they are still available in certain markets, and their scarce status is subject to change.  All rare coins are scarce, but not all scarce coins are rare. Rarity often depends on historical context, demand, and collector interest.

To remember the difference between rare and scarce coins, note that scarcity is determined by availability at a particular time, while rarity is a more permanent state barring the discovery of a new coin hoard.

What Makes a Coin “Scarce?”

A scarce coin is a coin that is not necessarily rare, but is hard to find in the marketplace either because it is highly collected and/or just is not available at a particular time. Just because scarce coins are not widely seen in circulation, does not mean they are considered rare in the numismatic market. Also, while rare is a well-recognized term in the numismatic industry, the term scarce is not a formal or technical term, though it is commonly used to describe coins that are hard to find at a particular moment.

What Defines a “Rare” Coin?

Like scarce coins, rare coins are difficult to find, but their scarcity comes from a low initial mintage and/or low surviving population (meaning portions of their mintage were lost over time either due to heavy circulation or mass meltings).  Unless some unknown hoard of the rare coin is found, rarity is a fairly permanent state, unlikely to change. 

In rare coin collecting, rarity is often measured by more than just production numbers; factors such as survival rate, collector enthusiasm, and auction history can play significant roles. Examples of rare coins include:

  • 1794 Flowing Hair Silver Dollar

The Flowing Hair Silver Dollar was the US federal government’s first coin, and only four known copies with a PCGS grade of 65+ exist. The design features a portrait of Lady Liberty on the obverse and an eagle on the reverse. One 66+ PCGS grade Flowing Hair Dollar sold for nearly $5 million in 2015. 

  • 1943 Lincoln Head Copper Penny

1943 Lincoln Head Copper Pennies are extremely rare—only 40 copies are known to exist. Coin experts believe these coins were struck by accident when copper blanks were left in the press while production of the new steel pennies began. The most expensive 1943 Lincoln Head Copper Penny ever purchased was for $82,500 in 1996.

  • 1913 Liberty Head V Nickel

The 1913 Liberty Head V Nickels are a numismatic mystery—no one knows how or why they were produced. The new Buffalo design replaced the old “V” nickel design that year. No Liberty nickels with the 1913 date were approved for production. Only five of these coins were ever produced and are generally considered some of the most valuable coins in the world. Two of these specimens sold for over $3 million each.

  • 2007 $1M Canadian Gold Maple Leaf

In 2007, the Royal Canadian Mint produced five $1 million (CAD) coins known as the Big Maple Leaf. The Big Maple Leafs claimed the Guinness World Record title as the world’s biggest gold coins with an incredible gold purity of 99.999%, making it one of the rarest gold coins to exist. As with other rare coin values, the market value of the 2007 $1M Canadian Gold Maple Leafs has reached more than $1M of its face value—sometimes four times that price. Source
