Almost everyone who finds an old coin asks the same thing first: is this worth anything? The honest answer is that it depends, mostly on three things: what the coin is, what condition it's in, and what people have actually paid for one like it recently. A coin that looks identical to another can be worth very different amounts because of a tiny mint mark or a few hairline scratches.
This guide walks through the same steps a dealer goes through, so you can get a realistic range on your own before you talk to anyone. If you'd rather have someone look, you can send us photos for a no-obligation look.
Step 1: Don't clean it
Before anything else: leave the coin exactly as it is. Cleaning, polishing or rubbing a coin removes its original surface, and graders and collectors treat cleaned coins as impaired. A dull or toned coin is often worth more than the same coin scrubbed bright. Hold coins by the edges, and store them in a soft holder or envelope, not loose in a jar.
Step 2: Identify exactly what you have
You can't price a coin until you know precisely what it is. Note these four things:
- Country and denomination. "One Dime," "Quarter Dollar," "One Dollar," or the foreign equivalent.
- Date. Usually on the front (obverse).
- Mint mark. A small letter such as P, D, S, W, O or CC that shows where the coin was struck. Its location varies by series, so look near the date and on the back (reverse). The same date can be common with one mint mark and scarce with another.
- Design or type. For example, a Morgan dollar versus a Peace dollar, or a bullion Silver Eagle versus a proof.
Reference sites like PCGS CoinFacts and the NGC Coin Explorer let you search by series and date to confirm what you have and see the known varieties. The printed "Red Book" (A Guide Book of United States Coins, published every year) is a good offline reference.
A quick metal check: U.S. dimes, quarters and half dollars dated 1964 and earlier were struck in 90% silver. Those coins carry a floor value tied to the silver price even when they're common dates. Most later circulating coins are copper-nickel clad.
Step 3: Judge the condition honestly
Condition, or grade, often matters more than the date. Professional graders use a 1–70 scale, where 70 is a flawless coin under magnification and low numbers mean heavy wear. You don't need to assign a number, but you can sort coins into rough groups:
- Heavily worn: details and lettering are flat or faint.
- Moderately worn: design is clear but high points are smooth.
- Little or no wear: sharp details, original luster (the cartwheel shine when you tilt it under a light).
- Problem coins: cleaned, scratched, bent, holed or corroded. These usually sell at a discount, sometimes a steep one.
Be conservative. Most people grade their own coins higher than a grading service would.
Step 4: If it's already graded, verify the slab
If your coin is sealed in a plastic holder from PCGS or NGC, the label already tells you the grade. Before you trust it, look up the certification number on the grader's own website (PCGS and NGC both let you verify certs online). The lookup should match the coin, date, grade and, for many modern coins, show an image. If it doesn't match, or the holder looks altered, treat it with caution. Our guide to PCGS vs. NGC Silver Eagles explains what the label terms mean, and MS70 Silver Eagle value covers why one grade point can matter so much.
Step 5: Check what similar coins actually sold for
Asking prices are wishes. Sold prices are evidence. Use more than one source:
- eBay sold listings. Search the exact coin (date, mint mark, grade and grader if slabbed), then filter to Sold items. Ignore outliers and look at the middle of the recent results.
- Auction archives. Major auction houses publish past results once you register. They're most useful for better coins.
- PCGS and NGC price guides. Good for a general picture by grade, but they're guides, not offers. Real sales can land above or below them.
When you compare, match like with like. A raw (ungraded) coin doesn't sell for the same as a graded one in the same condition, and a cleaned coin doesn't sell like an original one. That's why any honest value is a range, not a single number, and why it shifts with the grade.
Step 6: Understand the difference between value and an offer
Even once you have a range, the amount someone will pay you depends on how you sell. Selling to a dealer is fast and certain, but a dealer needs room to resell, so offers come in below retail. Consigning or auctioning can bring more but takes time and carries fees. Selling privately takes the most effort and carries the most risk.
Grading can add value to the right coin, but it costs money and time. It usually makes sense only when the coin's likely value in a high grade is well above the cost to grade it. Our article on raw vs. graded lays out both sides.
When to ask for a second opinion
Get a hands-on look if you have:
- An inherited collection or a large group of coins.
- Anything that might be gold, an early date, or a key date in a popular series.
- A coin you think may be a rare variety or an error.
- A slab whose cert lookup doesn't match.

FAQ
How can I tell if my old coin is valuable?
Identify the exact date, mint mark and design, judge its condition honestly, then compare recent sold prices for the same coin in similar condition. Silver content, low mintage dates, high grades and rare varieties are the usual sources of value above face.
Are coins dated before 1965 worth more?
U.S. dimes, quarters and half dollars dated 1964 and earlier are 90% silver, so they're worth at least their silver content, which moves with the silver price. Collector value above that depends on the date, mint mark and condition.
Should I clean my coin before having it valued?
No. Cleaning removes the original surface and usually lowers the value. Leave it as it is and handle it by the edges.
Is a price guide value what I'll get paid?
Not usually. Price guides are a general reference by grade. What you receive depends on recent real sales and how you sell. A dealer offer is typically below retail because the dealer has to resell the coin.
Is it worth getting my coin graded?
Sometimes. Grading costs money and takes time, so it usually makes sense only when the coin could be worth noticeably more in a certified high grade than the total cost of grading and shipping.
Can you tell me what my coin is worth from photos?
Photos are enough for a rough range on many coins. A firm offer comes after we see the coin in hand, because small details like cleaning or hairlines are hard to judge on screen.
Values for collectible coins change with the market and depend on grade. Nothing here is an offer or investment advice.
