Benefits Of A Coin Microscope
If you are grading coins on a professional basis, you need to investigate minute errors and variances on coins.
Or, you may simply want to highly scrutinize your coins. A coin microscope is a great purchase.
When it comes to picking out the very best coins for your collection or investment portfolio, you need to gain a focus right to the tiniest detail.
Coin microscopes help you to spot things that you may not see so easily — if at all — through a regular magnifying glass.
Things You Can See With A Coin Microscope
Here are some of the things a coin microscope can help you clearly see:
- Flow lines: Minute lines that occur on the coin after striking; their absence on an uncirculated coin or coin with only slight wear may mean the coin has been abrasively cleaned.
- Die-polishing marks: Raised lines or swirls on a coin produced by cleaning of the die, which is the stamp that produces an image on a coin.
- Slight errors: A mistake produced on a coin while still at the mint. Many errors are very valuable.
- Traces of mintmarks: A mintmark (or lack thereof) indicates where a coin was struck. On some coins, like the 1922- no mintmark (“plain”) penny, the complete absence of a mintmark makes for very valuable coins.
- Evidence of counterfeiting: Often detected through the discovery of added or removed mintmarks, date digits, or other lettering and design details. Also, counterfeiting can be detected on coins which appear to be manufactured outside the mint.
All of the above (and other elements) are the crucial issues that professionals consider when examining coins. What is more, all of these variables are best seen through a high-powered, well-made coin microscope.
A Good Coin Microscope Is Worth The Price
A good microscope can cost you well into the hundreds of dollars.
However, if you are someone who relies upon looking at and investigating every last detail on your coins, it really is well worth the money to consider buying a coin microscope.
A coin microscope is a fantastic buy for studious coin collectors and professional scrutinizers.
Still, in my opinion, the average collector really does not need to spend the money on a coin microscope.
Detecting Counterfeit Coins
As you may know, third-party graders examine the coins they put into their tamper-evident containers called slabs.
Therefore, anyone buying a coin in a slab need not worry much about buying a counterfeit coin, unless somehow the slab has been breached by an unscrupulous individual.
Such a situation would be rather obvious, due to damage that would usually be seen on the slab.
So… Coin Microscope Or Magnifying Glass?
For the inexpensive, unslabbed coins I purchase, I’m not that worried about counterfeiting.
I’m more concerned about cleanings, nicks, bruises, discoloration, dings, and other damage usually visible under low magnification — and very often quite evident to the trained, naked eye.
I do enjoy studying the details on my coins, but even this can be satisfactorily handled with a 5-10X coin magnifying glass or coin loupe.
Coin magnifying glasses and coin loupes can be purchased from most any coin dealer (both online and at a physical store) for less than $25.

My love for coins began when I was 11 years old. I primarily collect and study U.S. coins produced during the 20th century. I'm a member of the American Numismatic Association (ANA) and the Numismatic Literary Guild (NLG) and have won multiple awards from the NLG for my work as a coin journalist. I'm also the editor at CDN Publishing (a trusted source for the price of U.S. rare coins), editor at the Florida United Numismatists Club (FUN Topics magazine), and author of Images of America: The United States Mint in Philadelphia (a book that explores the colorful history of the Philadelphia Mint). I've contributed hundreds of articles for various coin publications including COINage, The Numismatist, Numismatic News, Coin Dealer Newsletter, Coin Values, and CoinWeek. I've also authored nearly 1,000 articles here at The Fun Times Guide to Coins — and I welcome your coin questions in the comments below!
