Inherited a coin collection? Found old coins in a jar? Some are worth face value. Others are worth thousands. Here's how to tell.
Any US coin dated 1964 or earlier that's a dime, quarter, or half dollar is made of 90% silver. At current silver prices, these are worth at minimum $2-10+ just for the metal content, regardless of numismatic value.
Error coins — misprints, double dies, off-center strikes, wrong planchet errors — can be worth hundreds to thousands regardless of age.
Key dates — certain years and mint marks are rare. A 1909-S VDB Lincoln penny is worth $800+. A 1916-D Mercury dime is worth $1,000+.
Identify the coin. Note the year, mint mark (small letter — D for Denver, S for San Francisco, no mark for Philadelphia), and denomination.
Check the grade. Coin grading runs from Poor (P-1) to Mint State (MS-70). Higher grades are exponentially more valuable. Key factors: wear on high points, luster, and contact marks.
Look up sold prices. PCGS CoinFacts and NGC Price Guide are industry references. For market prices, check eBay sold listings for your exact coin, year, and approximate grade.
