Projected Collection Value
Collection Value Growth
Future Value = Current Value x (1 + Annual Rate)^Years
Historical numismatic appreciation (long-term averages):
- Common circulated coins: 1–3% per year (roughly tracks inflation)
- Key-date U.S. coins: 5–10% per year historically
- High-grade rarities (MS-65+): 8–15% per year in strong markets
- World coin rarities: highly variable
Note: Coin values are cyclical and do not guarantee straight-line growth. The above are long-term historical averages, not guarantees of future returns.
