One coin sold for $10 million in 2013, and experts believe a pristine specimen could fetch over $13 million at auction. The elegant “Flowing Hair” design adds to its timeless appeal.
3. 1913 Liberty Head Nickel (Hawaii Five-O Coin)

Frequently Asked Questions
Q1: How do I know if my coin is valuable?
Check the coin’s date, mint mark, and condition. Coins with low mintage, historical significance, or minting errors usually hold more value. For certainty, have your coins authenticated by professional grading services like PCGS or NGC.
Q2: Where can I sell an ultra-rare coin?
High-value coins are best sold through reputable auction houses such as Heritage Auctions, Stack’s Bowers, or GreatCollections, where you can reach serious collectors worldwide.
Q3: Are all old coins valuable?
Not necessarily. Age alone doesn’t determine value. Condition, rarity, and collector demand play much larger roles in a coin’s worth.
Q4: Could there be more undiscovered ultra-rare coins?
Absolutely. Some of the world’s most valuable coins were found unexpectedly. Always examine unusual coins carefully before buying, selling, or spending them.
