I Inherited a Coin Collection. What Should I Do First?
The short answer
Do nothing for a week. Don't clean a single coin, don't crack a slab or open the mint packaging, and don't accept the first offer, least of all from someone who came to you.
Then sort the collection into five piles, get a fee-based appraisal on anything substantial, and sell each pile where it brings the most. Selling everything to one buyer at once typically costs 30–50% against routing it properly.
What should you avoid in the first week?
The instinct is to find out fast what it's worth and turn it into cash. Resist it for seven days. Three mistakes happen in that window, and all three are expensive.
Cleaning. It's the single most costly thing you can do to a coin, and you can't undo it. A cleaned coin gets graded as "details," which often halves its value. Graders spot it every time. Leave the tarnish alone.
Cracking slabs or unpacking coins. Slabs, the government GSA boxes some Morgan dollars came in, and original mint packaging carry their own premiums. A 40-year-old proof set is worth more in the box it came in.
Taking the first offer. Especially from someone who heard about the estate and got in touch with you. The person who approaches you first is rarely the one who pays best.
How do you sort an inherited coin collection?
Sort before you value anything. Five piles:
- Slabbed coins. Already graded and the easiest to price. Look up each certification number on the grader's website, then check recent sold prices for that coin in that grade.
- Bullion. Anything obviously gold or silver by weight and date, including pre-1965 dimes, quarters and halves, which are 90% silver.
- Possible keys. Check dates and mintmarks against the key-date lists for each series. This pile is small and it matters most.
- Common material. Wheat cents, worn Buffalo nickels, circulated commons, modern mint sets.
- Non-coins. Paper currency, tokens and medals. They have separate markets and separate specialists.
That one sort turns three boxes on a kitchen table into four manageable jobs and one small pile that deserves a professional's eye.
How do you get an honest value?
For anything substantial, pay for an appraisal from someone who is not also offering to buy. Fee-based appraisals are usually billed hourly. A free appraisal from a dealer is really an offer. That isn't because dealers are dishonest. Nobody can be the person setting the value and the person paying it at the same time.
You'll need a fee-based document anyway if the estate needs a value for insurance or for the filing.
If you'd rather skip the appraisal, the fastest safe route is a local coin shop with a physical storefront, years of reviews, and ideally membership in the American Numismatic Association or the Professional Numismatists Guild. Don't bring everything. Bring one representative pile, ask what they'd pay and why, and listen for reasons in the answer. Then take the same pile to a second shop.
Two honest offers on the same coins usually land close together. A predatory offer stands out next to an honest one, and two visits are enough to show you which is which.
Do you owe tax when you sell inherited coins?
Often very little, and this surprises most heirs. Inherited property generally gets a basis equal to its fair market value on the date of death, under IRS rules. If you sell soon after, the gain is often small or zero.
That flips the usual thinking. A collection is frequently worth more sold soon than held, because holding exposes you to gains above that stepped-up value and to the price swings of metal.
One reporting rule to know if you sell to a dealer for cash: a business that receives more than $10,000 in cash in one transaction, or in related transactions, files IRS Form 8300. It's the dealer's filing, not a tax on you, but it's why large cash deals come with paperwork. This isn't tax advice; for a large estate, talk to the estate's accountant.
Where should each pile be sold?
Each pile has a different best buyer.
Slabbed keys and four-figure coins get consignment quotes from an auction house, or careful eBay listings with good photos. Commission for reach is a fair trade at that price level.
Bullion goes to a dealer at a tight spread. On September 2, 2026, posted bids for a 1 oz American Gold Eagle ran 93–99% of spot, and pre-1965 90% silver brought $30–$42 per $1 face value. Get two quotes and lock the price by phone.
Common material moves in bulk, as lots on Whatnot or to a shop by the box.
If the collection is large and you need it gone fast, selling it all to one buyer is a legitimate choice. Just make it on purpose. It typically costs 30–50% against routing each pile to the right buyer.
Questions people also ask
Should I clean inherited coins before selling them?
No. Cleaning is permanent, graders detect it, and a cleaned coin is graded as details, which often halves its value. Sell coins exactly as you found them.
Is a free coin appraisal from a dealer reliable?
Treat it as an offer, not an appraisal. For an honest value, pay a fee-based appraiser who is not also offering to buy, or get quotes on the same coins from two shops.
Do I pay capital gains tax on inherited coins?
Inherited property generally takes a basis equal to its fair market value at the date of death, so a prompt sale often produces little or no taxable gain. Confirm the details with the estate's accountant.
Should I sell an inherited coin collection all at once?
Only if speed matters more than money. Selling everything to one buyer typically costs 30–50% against sorting the collection and selling each part to the buyer who pays most for it.
