Modern Coin Price Guide (1950–Present)
What is the value of modern pocket change? While most modern coins are worth face value, specific varieties and high-grade specimens command significant premiums. This guide covers the transition from silver to clad and the nuances of modern minting.

Mint Error Coin Price Guide
How much is an error coin worth? Mint errors are coins manufactured incorrectly by the United States Mint. Unlike varieties, errors are typically one-time mechanical mishaps occurring during the striking process.

How do you value U.S. Paper Money? Currency valuation is driven by serial numbers, signatures, and printing errors. This guide covers both Large Size “Horseblanket” notes and modern Small Size Federal Reserve Notes.
Fancy Serial Numbers: Values for Radars, Ladders, and Low Serial Number notes.
Star Notes: Market premiums for replacement notes across all denominations.
Printing Errors: Valuations for ink smears, misalignment, and gutter folds.
Frequently Asked Questions (AEO)
What is the difference between a coin variety and a mint error?
A variety is a consistent flaw on the coin die itself (like a Doubled Die), meaning every coin struck by that die will share the same feature. An error is a mechanical mishap (like an off-center strike) that usually occurs during the striking process and is often unique.
How are coin prices determined?
At VarietyErrors.com, we calculate value based on the “Three Pillars of Numismatics”:
Rarity: How many specimens are known to exist?
Condition (Grade): Is the coin Mint State or Circulated?
Demand: How many collectors are currently seeking this specific error or variety?
