Rare Coin Grading Services and Paper Currency Grading Services
Verified Authenticity and a Guaranteed Grade
Rare Coin Grading and Paper Currency Grading is one of the most important and difficult skills required of a rare coin dealer. The quality or grade of a rare coin or paper currency note is the single greatest factor impacting its value. There are third party companies that offer coin grading and coin certification services, meaning they authenticate and numerically grade the condition of the coin. These are referred to as slabbed coins and notes, encased in a sealed plastic holder or sleeve and labeled with a numerical grade from Poor-1 to Mint State-70.
There are a multitude of coin grading services and paper currency grading service companies in the market, many of whom are considered less precise in their coin grading standards. Many of the rare coin grading services listed at the bottom of the page are known for inflating the grades. They also often ignore a number of grading criteria addressed by the major grading companies (PCGS, NGC and ANACS for coins, and CGA and PCGS Banknote), such as cleaning or environmental damage. Because of these less rigorous coin grading standards, some rare coin dealers are reluctant to purchase coins certified by these “off-brand” companies, and if they do make an offer, it is often well below the true value of the coin.
To give you an example of the kind of precision necessary to establish an exact grade for a coin, we have provided links to the PCGS and NGC coin grading standards below.
These grading standards are much more exacting than those of other grading services, making the grades assigned by PCGS, NGC and ANACS more accurate. This translates into more confidence for the collector, and a higher value for the coin. Our rare coin buyers and paper currency buyers grade based on these exacting standards, and many of our dealers have attended advanced coin grading and counterfeit detection classes offered by the American Numismatic Association.
