Key Takeaways
If you’ve been around coin collecting for any length of time, you’ve undoubtedly encountered the notion of coin grading. Grading services like the Professional Coin Grading Service (PGCS) and the National Guaranty Corporation (NGC) have issued official grades for more than 100 million coins during their collective times of service, and both organizations are considered the gold standards for certifying the condition, rarity, and authenticity of collectible coins.
In some cases, the coins you acquire may already be graded by one of these services. However, the ones you buy without preexisting grades present an obvious question. When should your coins graded by the PGCS or NGC?
| Coin Attribute | Grade? | Why Grade or Not Grade |
| Rare or Key Date | Yes | Certification protects rarity and authenticates condition |
| Near-Perfect Condition | Yes | High grades boost market value significantly |
| Investment-Grade | Yes | Graded coins sell quicker, often at higher prices |
| Verified Mint Error | Yes | Recognized errors gain credibility and value when graded |
| Sentimental Value | Optional | Provides secure protection for personal reasons |
| Common Modern Bullion | No | Value is mostly the metal; grading cost rarely justified |
| Heavily Damaged Coin | No | “Details” grades do not add enough worth |
| Low-Value Coin | No | Grading cost often exceeds any value increase |
Before you engage one of the two grading services mentioned above, you should understand independently what your holdings are. Use Google, post on Reddit, or visit a local coin shop to find out information about your coin’s year/mintage, the location of its mint, the possibility that an error is present (and know which one(s)), and that all three of its edges – obverse, reverse, and edge – conform to the accepted design parameters of your coin.
The more you know about your coin before you send it to the NGC or PGCS, the better.
You should consider getting a coin graded if the potential value outweighs the cost of having the procedure done. Both the NGC and PCGS charge between $20 – $70 for grading, depending on the rarity of the coin you submit, and some extremely rare coins may require an even greater expenditure.
You may also have to contend with a membership fee, depending on the level of service you want. Both organizations are for-profit entities, and they understandably give preference to customers willing to come further out of pocket.
Here’s a breakdown of coin grading costs and ancillary fees, organized by service tier and for each major grading company (PCGS and NGC). These are estimates and we encourage you to look at the breakdown of information on the coin grading website.

Getting a coin graded should not be an additional expense that lowers the aggregate value of your collection. You should expect that the appreciation in value yielded by the grading will be greater than its cost.
In other words, don’t bother with getting a coin graded if a certificate of authenticity means the price goes from $5 to $7. Reserve your funds for those truly rare pieces that might go from good coins to great coins.

The only time that you may want to get your coin(s) graded – even if the value may not support it – is if counterfeit versions of your coin are common. If you discover that your coin is, indeed, a forgery, you may be able to pursue recourse from the seller or through the legal system.In particular, be wary if you receive the coins for free, either through an inheritance or gift. If your buyer relative is not a sophisticated investor, there is a greater chance that they may have fallen victim to an unscrupulous coin dealer or, worse, another private entity.
