What Are Slabbed Coins?

To people who are new to investing in coins and precious metals, slabbing coins might sound like part of the minting process. However, it refers to a coin that has undergone certification. If you plan on buying or selling rare coins, there are a few advantages to investing in slabbed coins.

The Slabbing Process

Coins that have been submitted to a professional grading service for certification are examined by experts and assigned a grade based on several factors. After authentication, the coin will be sonically sealed in a clear “slab” or holder and will include essential information, such as the coin’s type, grade, variety, mint mark, and the third-party grading service’s information. Coin slabs are intended to be permanent holders for the coin and are usually difficult to tamper with once sealed. The Professional Coin Grading Service (PCGS) or the Numismatic Guaranty Corporation (NGC), the two leading third-party grading services, make it easy to further verify the authenticity of a slabbed coin. Both sites provide the user with the ability to type in the serial or certification number of a coin, which, if accurate, will provide details of the coin along with pictures.

Slabbed Coins vs. Raw Coins

Aside from choosing between coins made out of gold, silver, or another precious metal, collectors also have to decide whether to buy “raw” or slabbed coins. Slabbed or certified coins have been authenticated and graded by a reputable third-party service, such as the PCGS or NGC. Both slabbed and raw coins can be held in various protective cases, but a raw coin will not be in a sealed holder with a verified grade from a professional grading service.

What Are the Advantages of Slabbed Coins?

Although investors have to pay to slab their coins, there are several obvious benefits. Placing coins in a sealed container can protect them against physical damage from normal wear and tear or from being dropped. However, it’s important to note that silver and copper coins may still be damaged by toning if the container isn’t airtight. Slabbed coins offer collectors a higher level of assurance when it comes to the authenticity and resale value of their coins, which reduces the need for further inspection when selling them to a coin dealer. Lastly, certified coins remove subjectivity with respect to the grade and, subsequently, the value of the coin. It’s quite common for two parties to have a different opinion as to the grade of a coin that has not been certified.
