Inheriting a coin collection can feel overwhelming. You may have boxes of albums, rolls of coins, loose change mixed with rare pieces, and no idea where to start. The good news is that you do not need to be a coin expert to get a fair price — you just need to know the right steps and the right people to talk to.
At Clemson Coins, Currency and Bullion in Pendleton, South Carolina, we work with families across Greenville, Anderson, Clemson, Spartanburg, and all of Upstate SC who have inherited collections of every size. Here is exactly what we recommend.
Step 1: Do Not Clean Anything
This is the single most important rule in numismatics. Never clean a coin. Even gentle polishing with a soft cloth can destroy the original surface — called the "mint luster" — and reduce a coin's value by 50% to 90% or more. A coin that looks dull or dirty to you may be worth thousands of dollars in its original, uncleaned state. Cleaned coins are immediately identifiable to dealers and grading services and are worth a fraction of their uncleaned counterparts.
Leave everything exactly as you found it.
Step 2: Keep Everything Together
Do not throw anything away before having it evaluated. What looks like a jar of old pennies might contain key-date Lincoln cents worth hundreds of dollars each. What looks like a worn silver dollar might be a rare date worth thousands. Common coins and rare coins often look nearly identical to the untrained eye.
Keep all albums, folders, rolls, envelopes, and loose coins together until a professional has reviewed them.
Step 3: Look for Any Documentation
Check for any paperwork that came with the collection — purchase receipts, appraisals, certificates of authenticity, grading slips from PCGS, NGC, PMG, or other services. These documents can significantly help establish value and provenance. Also look for any notes the original collector may have left about specific pieces.
Step 4: Understand the Basic Categories
Most inherited collections contain a mix of:
- Circulated common coins — face value to modest premiums; includes wheat pennies, buffalo nickels, Mercury dimes, Walking Liberty halves
- Silver coins — pre-1965 U.S. dimes, quarters, and half dollars are 90% silver and worth multiples of face value based on the current silver spot price
- Key date and semi-key date coins — certain dates and mint marks within common series that are rare and highly valuable
- Gold coins — U.S. gold pieces ($2.50, $5, $10, $20 denominations) are sometimes worth significant premiums over their gold melt value while most are just bullion coins unless of exceptional high quality
- Proof and uncirculated sets — mint-issued collector sets from the 1950s onward
- World coins — foreign coins ranging from common to rare depending on country, date, and condition
- Paper currency — old bills, silver certificates, large-size notes, and star notes mixed in with coin collections are often overlooked and can be quite valuable
- Certified coins — coins in PCGS, NGC, CACG, CAC, ANACS, or ICG holders are already graded and authenticated
Step 5: Do Not Rush to Sell
Take your time. The coins are not going anywhere. A hasty sale — especially to the first buyer you encounter — is the most common way families leave significant money on the table. Get multiple opinions if you have any doubt and see Joe last, at Clemson Coins, Currency and Bullion for your best offer.
That said, do not wait so long that the collection sits in a non-climate-controlled environment where humidity and temperature swings can damage coins and paper currency over time.
Step 6: Avoid These Common Mistakes
Selling to a pawn shop — Pawn shops are generalists. They typically offer well below market value on coins because coins are not their specialty.
Selling at a garage sale or flea market — Rare coins sold this way almost always go for a tiny fraction of their true value to dealers who know exactly what they are buying.
Mailing coins to a "we buy coins" mailer — These operations rely on sellers not knowing what they have. Once your coins are in the mail, you have lost control of the transaction.
Splitting the collection before evaluation — Family members dividing up a collection before it is appraised can inadvertently separate key pieces from their context and reduce overall value.
Accepting the first offer — Always get at least one other opinion on a significant collection. A reputable dealer will not pressure you to decide on the spot. Get other offers and then come to Clemson Coins, Currency and Bullion last.
Step 7: Get a Professional Evaluation
Bring the collection to a specialist — not a generalist. At Clemson Coins, Currency and Bullion, we have decades of experience evaluating inherited collections of every type and size. We buy everything from single key-date coins to seven-figure collections.
When you bring your collection to us:
- We examine every piece carefully
- We identify key dates, mint marks, and varieties
- We check current PCGS, NGC, CACG, CAC, ANACS and ICG values and auction market data
- We separate bullion-value items from collector-premium items
- We give you a transparent, itemized explanation of our offer
What About Getting Coins Graded First?
For coins potentially worth $300 or more individually, professional grading by PCGS or NGC can increase value and make selling easier. As PCGS Dealer Members, NGC Authorized Dealers, CACG & CAC Authorized Dealers, we can advise you on whether grading makes financial sense for specific pieces in your collection.
For most inherited collections, grading every coin is not necessary — and the cost of grading common coins would exceed any benefit. We will tell you honestly which pieces are worth grading and which are not.
