How do I avoid getting ripped off when selling coins?

Updated October 2026 · How we answer

Short answerEducate yourself on coin values, get multiple offers, and use reputable dealers or grading services. Avoid high-pressure buyers and always get a written agreement.

Know What You Have

Before selling, identify your coins using a coin catalog or online price guides. Look at the date, mint mark, and condition. Even a small difference in condition can change value dramatically. For example, a 1909-S VDB Lincoln cent in good condition might be worth $500, but in mint state it can be thousands.

Consider getting a professional appraisal if you have many coins or suspect a rare one. Appraisals cost $25–$100 per hour, but they can prevent you from selling a valuable coin for pennies. Some dealers offer free verbal appraisals to entice you to sell to them, but get a second opinion.

  • Use a coin catalog like the Red Book
  • Check recent auction prices on eBay or Heritage
  • Look for mint marks and key dates
  • Assess condition: wear, scratches, cleaning
  • Get a professional appraisal for rare coins

Shop Around and Protect Yourself

Get offers from at least three different dealers or coin shops. Prices can vary by 20–50% or more. Don't accept the first offer unless you're confident it's fair. For valuable coins, consider consigning to an auction house that specializes in coins; they often get higher prices but charge a commission.

Always get a written receipt that describes the coins and the agreed price. If selling online, use a reputable platform with buyer/seller protection. Be wary of buyers who want to pay by wire transfer or cryptocurrency only, as these are hard to reverse if something goes wrong.

  • Get at least three offers
  • Ask for a written purchase agreement
  • Use insured shipping with tracking
  • Avoid high-pressure 'today only' offers
  • Check dealer reviews with the BBB or coin forums

Common mistakes

  • Selling to the first dealer without comparing offers.
  • Cleaning coins to make them look better, which actually reduces value.
  • Believing that all old coins are valuable; many are common and worth face value.
