Every expert was once a beginner, and in the world of numismatics, beginner mistakes can sometimes be expensive. Here are the most common pitfalls to avoid when starting your coin collection.
1. Cleaning Coins
This is the number one sin of coin collecting. Using polish, acid dips, or even baking soda ruins the coin's surface and destroys its premium value. Leave the patina alone.
2. Buying Without Research
Do not buy a coin just because it looks old. An 1800s coin might only be worth its metal weight if millions were minted. Always check the mintage numbers and recent auction values before purchasing.
3. Mishandling Coins
Touching the face of a coin leaves acidic fingerprints that can permanently etch into the metal. Always handle coins by the rim, preferably wearing clean cotton gloves.
4. Storing in PVC
Cheap plastic flips often contain PVC. Over time, PVC releases gases that create a sticky green residue on coins. Always invest in Mylar or archival-safe holders.
5. Falling for "Unsearched" Rolls
Online marketplaces are flooded with "unsearched bank rolls" promising rare errors or silver pieces. Almost all of these have been heavily searched by the seller. Stick to buying specific, graded coins from reputable dealers.
