Rare coins often have limited mintage. Research the coin’s production numbers to determine its rarity.

Some coins have variations in design or details (e.g., different lettering or portraits) that can affect their value.
Rare coins are usually harder to find. Consult numismatic catalogs or experts to gauge the rarity of the coin in question and its value in the market.
