Your Guide to Coin Collecting
Whether you're just starting out or looking to sharpen your knowledge, these resources will help you collect with confidence.
Why Education Matters
Coin collecting is one of the most rewarding hobbies in the world — but it can feel overwhelming at first. Knowing how to evaluate a coin, spot a fake, or understand what makes a piece rare can mean the difference between a great find and a costly mistake.
At LaMarca Numismatics, we believe every collector deserves to feel informed and confident. These resources are here to help you build that foundation.
Getting Started
Start with What You Love
The best collections are built around personal passion. Whether it's ancient Rome, American history, or world currencies — start with what excites you. Focused collections are more meaningful and often more valuable than random accumulations.
Set a Budget
You don't need to spend a fortune to build a great collection. Many stunning coins are available for under $50. Decide on a budget before you start shopping and stick to it — the hobby should be enjoyable, not stressful.
Buy from Reputable Dealers
Always purchase from established dealers who stand behind their coins. Look for sellers with strong feedback, clear return policies, and a willingness to answer your questions. A trustworthy dealer is your most valuable resource.
Understanding Coin Grading
The Sheldon Scale
Coins in the U.S. are graded on the Sheldon scale from 1 (Poor) to 70 (Perfect Uncirculated). A higher grade generally means better preservation and higher value. Grades like MS-65 (Mint State) or PR-70 (Proof) represent the finest examples.
Key Grading Factors
Graders evaluate strike quality, surface preservation, luster, and eye appeal. Even small differences in grade can significantly affect a coin's value — an MS-64 Morgan Dollar might be worth $100 while an MS-66 of the same date could fetch $1,000 or more.
Third-Party Grading Services
For valuable coins, consider submitting to a professional grading service like ANACS or NGC. A certified grade in a tamper-evident holder ("slab") adds credibility and makes the coin easier to buy and sell. LaMarca Numismatics offers submission services for both.
Spotting Fakes & Altered Coins
Weight & Dimensions
Counterfeit coins often fail basic physical tests. A precision scale and calipers can quickly reveal coins that don't match published specifications. This is especially important for gold and silver coins where the metal itself has intrinsic value.
Surface Alterations
Watch for coins with altered dates or mintmarks — a common way to turn a common coin into a rare one. Look for uneven surfaces, tool marks, or inconsistencies in the font under magnification.
When in Doubt, Ask
If something feels off about a coin, trust your instincts. Reach out to an experienced dealer before purchasing. We're always happy to offer a second opinion — no purchase necessary.
Storing & Caring for Your Collection
Never Clean Your Coins
Cleaning a coin — even gently — almost always reduces its value. Collectors and graders prize original surfaces and natural patina. A coin with honest wear is far more desirable than one that's been polished or dipped.
Proper Storage
Store coins in acid-free holders, flips, or albums. Avoid PVC-based plastics, which can cause green slime damage over time. Keep your collection in a stable environment away from humidity, heat, and direct sunlight.
Handle with Care
Always hold coins by their edges — never touch the faces. The oils from your skin can cause long-term damage to a coin's surface. Cotton gloves are ideal for handling higher-value pieces.
