What Makes A Coin Rare, Collectible, and Valuable?

In this blog post we discuss the key elements that make a coin rare, collectable, and valuable.

  • Precious Metal – Gold/Silver/Platinum

  • Specific Dates and Mint Mark (a letter indicating where the coin was made)

  • Demand – How many collectors want the coin

  • Condition – Original, unaltered, uncleaned. Better condition, better value.

  • Eye Appeal – Is the coin appearance above average?

  • Original vs. Cleaned Condition– Cleaned coins are worth a small fraction of the value of original coins.

  • Varieties, Errors, Mistakes – Mint errors are often highly collectible.
