Found an old coin and have no idea what to do next? You are in the right place. Follow this simple six-step path — it is the same routine experienced collectors use every time a new coin lands in their hand.
The 6-Step Beginner Path
- Don’t clean it. Ever. Cleaning is the number one way beginners destroy value — a cleaned coin can lose half its worth or more. Leave the dirt, toning, and fingerprints exactly as they are.
- Find the date and mint mark. The date is on the front. The mint mark is a tiny letter (P, D, S, or none) — on most older coins it sits under the date or on the back. Date plus mint mark is what makes one coin common and its twin rare.
- Check the value guide. Look your coin up in our Coin Value Guides to see the key dates and the price ranges for each grade.
- Weigh it and try the magnet test. For pennies especially: copper cents weigh 3.11 grams, zinc cents 2.5 grams, and 1943 steel cents stick to a magnet while rare 1943 copper cents do not. Weight and a magnet separate the treasures from the fakes.
- Protect it. Hold coins by the edges only, and store them in a coin flip, capsule, or soft cloth — never loose in a drawer with other coins.
- Get it graded if it is a key date. If your coin matches a key date and looks genuine, have it certified by PCGS or NGC before you sell. Certified coins get full price; uncertified rarities get doubt.
That is the whole path. Take it one step at a time, and when you are ready, browse the value guides for the exact coin in your hand.
