If you're new to coin collecting or investing in silver, terms like AU, BU, and MS might seem confusing. These grading labels are essential for assessing a coin's condition, value, and collectibility. This guide simplifies these classifications to help you make informed purchases.
Why Coin Grading Matters
Coin grading evaluates a coin’s:
- Physical wear
- Strike quality
- Luster preservation
- Surface imperfections
Higher grades typically mean greater market value, especially for rare or historic coins like Morgan Silver Dollars.
