What Is Your Coin Worth?
Coins reward precision. Two coins from the same year can differ hundredfold based on a single letter, so the checker reads the date and mint mark before it estimates anything.
A coin's value comes from its date and mint mark, its series, its condition on the numismatic grading scale, and whether its metal content exceeds its collector value. Photograph both faces with the date and mint mark legible for the most reliable estimate.
What the checker reads
- Date, denomination, and series.
- Mint mark and its position for that series.
- Wear on the highest points of the design, which sets the grade band.
- Surface originality — lustre, toning, and signs of cleaning.
- Recognised error and variety indicators where visible.
Melt value versus collector value
| Coin type | What sets the price |
|---|---|
| Common-date silver or gold | Metal content and spot price |
| Scarce date or mint mark | Collector demand, well above melt |
| Recognised error variety | Specialist collector demand |
| Certified high grade | Population scarcity at that grade |
| Circulated modern base metal | Usually face value |
Do not clean coins
Cleaning removes original surfaces and is immediately visible to graders and experienced buyers. A cleaned coin typically sells for a fraction of an equivalent uncleaned one, and the damage cannot be undone.
This is the most common and most expensive mistake made by people valuing inherited coins.
Photographing coins
- 01Both faces, separatelyObverse and reverse each carry identifying detail.
- 02Diffuse light, no direct flashFlash blows out lustre and hides wear. Indirect light shows both.
- 03Close crop on date and mint markA third photo focused there resolves most identification ambiguity.
- 04Neutral backgroundGrey or black cloth avoids colour cast on the metal.
Frequently asked questions
- How do I find out what an old coin is worth?
- Identify the date, mint mark, and series, judge how much wear the high points show, then compare recent sold prices for that date and mint mark in comparable condition. Check metal value as a floor for silver and gold.
- Are old coins always valuable?
- No. Many were struck in the tens of millions and remain common. Scarcity of date, mint mark, variety, or grade creates value, not age.
- Should I get coins certified?
- Certification is worth it when the coin's value is high enough to justify fees, when authenticity matters, or when the difference between adjacent mint state grades is financially significant.
