Deciding to sell is the easy part; deciding how, to whom and on what terms is where sellers get underpaid. The mistakes are consistent — taking the first offer, cleaning coins to “improve” them, confusing an asking price with a price — and every one of them is avoidable with a little preparation.
This guide covers the process: preparation, the main selling routes, how to collect and compare offers, and the red flags worth walking away from. It is not financial, legal or appraisal advice, and it makes no promise about what your coins will bring — nobody can until the material is in front of them.
Know roughly what you have first
Every route rewards a seller who can name their material. “A box of old coins” invites a bulk offer for a box; a short inventory — what appears to be there, in roughly what state — invites real questions. That record does not need to be expert. Jeff Garrett's NGC column on handling inherited coins recommends starting with beginner-oriented price guides — his examples are the Blue Book, which tracks what knowledgeable buyers typically pay, and the Red Book, which lists retail values — and looking up the pieces that seem most valuable before approaching anyone.

A Coin Says Hi reading on a few representative coins is the same preparation in miniature: a provisional possible match gives you names to look up and a record of the visible clues — the identification guide shows how to keep that record, and the photo flow is where it starts.
One preparation step is forbidden: no cleaning. Dealers and grading services commonly read a wiped or polished surface as damage — NGC, for one, assigns details grades for improper cleaning — and the care guide explains why the impulse is so costly. NGC: Details Grading
Three routes: dealer, auction, private sale
Selling to a dealer is the fastest route and prices for it: a dealer buys to resell, so an offer reflects their margin as well as the coin. Finding them through professional directories is a reasonable starting filter — the Professional Numismatists Guild publishes a searchable member directory, and the American Numismatic Association maintains a coin dealer directory of member dealers. Membership means a member has agreed to a code of ethics; it is not a guarantee of a fair offer, which is why the next section exists. PNG: Member Directory, ANA: Coin Dealer Directory
Auction and consignment suit material with real scarcity or documented certification. Garrett notes that auction companies will often provide free estimates, and that consigning coins through a dealer can sometimes net more than a cash sale — because the dealer takes no risk on your material.

Selling privately or online keeps the margin but adds the work: listings, photographs, shipping, disputes and platform fees. Garrett's blunt version is that selling coins online is a business with real pitfalls; for a casual seller, the route earns its complexity only for material that justifies it.
No route is universally best — the material decides. Common circulated coins want the dealer or bulk path; a documented rarity deserves an auction estimate before anything else.
Match the route to the material
Fast; offer priced for resale; ask for the net
Suits scarce or certified pieces; estimates often free
Keeps the margin; adds listings, fees and risk

Getting and comparing offers
An offer is one buyer's proposal priced for their resale — information, not a market verdict. Garrett's method makes that practical: get offers on a smaller portion of a collection first, take the most promising pieces to more than one dealer, and say plainly that you are collecting offers — “if the dealer has an issue with this — move on.” NGC: When an Inheritance Arrives in Coins
Record each offer with who made it, when, and on what basis. Offers on gold and silver can be anchored to the day's bullion prices; Garrett advises having that basis stated alongside the offer so it can be compared a week later. The value guide explains the same discipline from the other side — completed sales and documented transactions outrank listings — and the professional-roles guide separates a dealer's offer from an appraisal entirely.
Fees and commissions in outline
Every route takes its cut differently, and the honest summary is “ask for the net figure.” A dealer's offer already has their margin inside it rather than an itemised fee. Auction houses charge commissions set out in their consignment terms — and buyers commonly pay a premium of their own, which affects what the final price can be. Private and online sales absorb listing, payment and shipping costs.
Ask each route the same question: after everything, what lands in my hand? Two offers that look far apart can close once commissions and fees are counted — and the route that looks cheapest on paper can cost the most in time.
Documentation that helps a sale
The record you built when identifying the material pays off at the table: clear photos of both sides and the edge, your candidate identifications, any holders or certificates, and provenance notes — where the coins came from and who kept them. For certified coins, the holder's certification record travels with the sale; buyers verify it.
Some situations need a formal appraisal rather than offers — estates, insurance and legal settlements among them. Garrett notes that certain circumstances call for a qualified appraiser, and that dealers sometimes make free “offers to purchase” that can serve the purpose; ask about fees before assuming either way. The professional-roles guide maps the boundary between what a dealer, a grader and an appraiser can each tell you.
Red flags and pressure tactics
Urgency is the loudest red flag in this trade: an offer that is “today only” is a reason to slow down, not speed up. Others worth naming: pressure to sell the whole lot before any inventory exists, reluctance to put a number or its basis in writing, a stranger who pronounces every coin valuable free of charge, and offers that dodge the question of whether they are tracking bullion or collector prices.
Keep the defences simple. Declining a proposal costs nothing before you commit, and the collection stays with you until the paperwork exists — but once you sign a consignment or auction agreement, withdrawal follows that agreement's terms rather than your preference: published auction-house seller terms can require consent to withdraw a lot and reserve withdrawal charges, so read the cancellation and withdrawal clauses before signing, consigning or accepting. Spink's terms directory links its UK seller terms as one published example. Spink: Terms and Conditions And give anything that might genuinely be rare a second route's opinion before it moves. If the material arrived through inheritance, the first-steps guide is deliberately sequenced to keep you from selling under exactly this pressure.
Questions people ask
Should I clean the coins before selling?
No. Cleaning removes original surface in ways buyers and graders read as damage, and it can cut a coin's saleability rather than raise it. Sell it as it is — the care guide explains the alternative.
Dealer or auction — how do I choose?
Let the material decide. Common circulated coins suit the dealer or bulk route; genuinely scarce or certified pieces deserve an auction estimate first — auction companies often provide those estimates free. For anything significant, collect both views before committing.
Is a dealer's offer the market price?
It is one buyer's proposal, priced for their resale — real information, but not a market verdict. Two or three offers on the same material are what turn it into a picture.
Can a Coin Says Hi reading help me sell?
As preparation, yes: a provisional possible match plus your written record is exactly what to bring to a first conversation. It is not an appraisal, and no buyer should treat it as one — readings do not authenticate, grade or value coins. Try it on a few coins before you make calls.
Sources and scope
Jeff Garrett's NGC column on inherited coins supports the preparation, multiple-offer, bullion-basis, consignment and appraisal points above. The PNG member directory and the ANA dealer directory are the starting filters named for locating dealers — inclusion in either is a membership signal, not this site's endorsement. Spink's published terms directory is cited as one auction house's example of seller withdrawal provisions; each house writes its own. The route comparison, net-figure habit and red-flag list are Coin Says Hi's editorial method. This article is not financial, legal or appraisal advice, and nothing here predicts what any coin will sell for. Sources last checked 2026-10-01.
