Mint State Coins: A Beginner's Guide to Collecting, Evaluating, and Investing

The world of numismatics is teeming with fascinating facets, from ancient coins to freshly minted specimens. Yet nothing captures the attention of collectors and investors quite like mint coins. Perfectly preserved, rich in detail and often endowed with incredible investment potential, these coins are the gold standard in the coin collecting world. This beginner’s guide is an invaluable resource for anyone interested in collecting, grading, and investing in Mint State coins.

What are Mint State Coins?

Mint State coins, often abbreviated as MS, are coins that have never been in circulation. They are in pristine condition and show no signs of wear, scratches or other signs of processing. These coins are graded on the Sheldon Scale, which ranges from MS-60, the lowest Mint State grade, to MS-70 , which corresponds to a coin in perfect condition.

Key Features of Mint State Coins

  • Luster : one of the most important characteristics of a Mint State coin is its luster – a natural luster created during the minting process. This luster is usually the first feature to disappear when a coin enters circulation.
  • Details : all the details of a freshly minted coin, from the small details in the background to the prominent figures and symbols, are sharp and intact.
  • Edges and Margins : An as-minted coin has sharp, well-defined edges and margins. They don’t show the dents, nicks or scratches that result from ending up in pockets or piggy banks.
  • Surface : the surface or field of the coin is free from scratches, stains or tarnish that could affect its appearance or value.
  • Minting : a coin’s minting refers to the clarity and sharpness of the design elements. Coins as minted typically have a sharp, complete strike, indicating high quality and attractiveness.

Grading of Mint State Coins

The grading of Mint State coins is a meticulous process that is often performed by professional grading services. The coins are examined under magnification and subjected to a number of criteria to determine their condition. While grading can be subjective, when a coin receives a high grade from a reputable service, its market value increases significantly.

Invest in Mint State coins

Mint State coins are very attractive to investors for several reasons:

  • Rarity : the rarity of a coin can increase its value exponentially.
  • Demand : Coins that are popular with collectors tend to maintain their value or even increase in value.
  • Historical Significance : Coins from significant eras or important events are often of higher value.

Before making any investment, you should always do your homework. Research the market, consult experts and understand the risks.

Taking care of your Mint State coins

Proper care is critical to maintaining the condition, and therefore value, of your Mint State coins.

  • Handling : Always handle coins by the edge and use cotton gloves.
  • Storage : Store the coins in acid-free containers and in a climate-controlled environment.
  • Documentation : Keep accurate records, including photographs and certificates of classification where applicable.


Whether you’re just starting out collecting or looking to add to your existing collection, mint coins offer a fulfilling experience that blends art, history and investment potential. It is essential for any aspiring numismatist to understand the basic elements that contribute to a coin’s Mint State and its resulting value.
