What is the difference between a variety and an error?
Varieties: Intentional or die-based differences
A variety occurs when the Mint intentionally changes a design or when a die is prepared with a different hub, creating a consistent difference that appears on all coins struck from that die. Examples include the 1909 VDB Lincoln cent (designer's initials added then removed) or the 1955 doubled die cent (a die hubbing error that became a variety because many coins were struck).
Varieties are cataloged by reference books like the Red Book or Cherrypickers' Guide, and they often have specific names like 'DDO' (doubled die obverse) or 'RPM' (repunched mintmark). Because they are die-specific, they can be found on thousands or millions of coins.
Errors: Unintended production mistakes
An error is a one-off mistake during the minting process, such as a broadstrike, off-center strike, clipped planchet, or a die crack that only affects a small number of coins. Errors are not intentional and are usually unique to a specific coin or a small batch.
Errors can happen at any stage: planchet preparation, striking, or even after striking (e.g., a coin that missed the upsetting mill). They are often more dramatic and can be worth more because of their rarity and visual appeal.
Key differences at a glance
The main distinction is intent and repetition: varieties are planned or die-related and repeat; errors are accidental and typically do not repeat. However, some errors, like a doubled die, can become varieties if they are striking enough and many coins are minted before the error is caught.
Collectors often specialize in one or the other, and pricing can vary widely. Varieties are usually listed in guides, while errors are often valued based on eye appeal and rarity.
- Variety: intentional design change or die difference, repeats on many coins.
- Error: unintended mistake during production, usually affects few coins.
- Some errors (like doubled dies) become varieties if many are struck.
- Varieties are cataloged; errors are often unique and not listed.
- Both can add value, but for different reasons.
Common mistakes
- Thinking all doubled dies are errors—many are classified as varieties because they were struck in large numbers.
- Assuming any odd-looking coin is an error when it could be a variety or just damage.
- Believing that varieties are always more valuable than errors; some errors can be worth more.
