Selling one inherited gun is a transaction. Selling a whole collection is a project — and the order you do things in matters more than any single decision. Rush the sale and you can leave thousands of dollars behind or create paperwork problems for the estate. This guide covers the full process, from the first day you open the safe to the day the last firearm is sold or transferred.
Step 1: Secure Everything Before You Decide Anything
Before any valuation, sale, or distribution, make sure every firearm is unloaded and locked up, with ammunition stored separately. If you are not comfortable checking a firearm yourself, do not guess — lock it where it is and get help from someone experienced or a licensed dealer.
Do not start handing guns to relatives at this stage, even with the best intentions. Once firearms leave the estate without documentation, sorting out who got what — and whether each recipient could legally possess it — becomes much harder. Secure first, decide second.
Step 2: Inventory the Whole Collection
Walk the collection item by item and record, for each firearm:
- Make, model, and caliber or gauge
- Serial number
- Condition, in plain terms: finish wear, rust, damage, missing parts
- Anything that came with it: original box, manual, extra magazines, scope, case
Photograph each firearm from both sides, plus close-ups of markings and serial numbers. This inventory is the estate record, the basis for valuation, and protection if a question comes up later. Flag anything unusual: fully automatic firearms, short-barreled rifles or shotguns, and suppressors fall under federal NFA rules — stop and get professional help before moving those. Do not clean or restore anything yet. Original condition is where collector value lives; refinishing or re-bluing can cut value sharply, so valuation should come before any work on a firearm.
Step 3: Get a Valuation for the Collection, Not Just a Price for One Gun
A collection valuation is different from a single offer. It gives you a fair market value for each firearm, based on actual recent sales of comparable guns, in writing. That matters for several reasons: the estate may need defensible values for probate or for dividing assets fairly among heirs, and you cannot choose between selling options sensibly until you know what the collection is actually worth.
A collection is rarely worth what the family guesses: some ordinary-looking guns are collectible, and some impressive-looking ones are common models worth a few hundred dollars. A written valuation replaces guessing with numbers, which makes every later conversation easier. Gun Legacy offers valuations as part of a free consultation.
Step 4: Decide the Path for Each Firearm
A collection does not have to go one way. In fact, it usually should not. Go through the inventory firearm by firearm and sort each one into a path:
Transfer to heirs. Firearms with sentimental value that a family member wants to keep and can legally possess. In Colorado, private transfers generally go through a licensed dealer (FFL) with a Colorado Bureau of Investigation background check, and documenting the transfer through a dealer creates a clean paper trail. Transfers to heirs upon the owner's death are also exempt from the SB25-003 eligibility-card requirement for covered semiautomatic firearms, which is covered in more detail in the seller's guide to that law.
Consignment. Firearms you want to sell for as much as the market will pay. A licensed dealer lists and sells them for you and takes a commission — at Gun Legacy, 20%, so roughly 80% of the sale price comes back to you or the estate. Consignment takes weeks to a few months, but for a collection, the difference over quick shop offers is often thousands of dollars in total.
Dealer sale. Firearms you need to move quickly, or low-value pieces where the extra return from consignment is not worth the wait. A gun shop typically offers 20–30% of market value in cash on the spot. That is a legitimate choice for a $150 gun you need gone today; it is an expensive choice for a collection.
Deactivation for display. Pieces with more sentimental value than market value — a grandfather's shotgun, a service rifle — that the family wants to keep visible but not functional. A gunsmith can render a firearm permanently inoperable so it can be displayed safely.
Step 5: Handle the Sale Properly
However you sell, a few rules apply across the board. In Colorado, private firearm transfers go through a licensed dealer with a background check. If you consign, the dealer handles the listing, the buyer, the transfer, and the paperwork — that is part of what the commission pays for. Keep a transfer log as you go: who received or bought which firearm, identified by make, model, and serial number, on what date, and through which dealer. File it with the estate records.
Be wary of a "free appraisal" from someone who wants to buy the guns — that is an opening bid, not an appraisal — and of pressure to decide on the spot.
Step 6: Close Out the Estate Record
When the last firearm is sold or transferred, reconcile the inventory: every item should have a disposition — kept by a named heir, sold through a named dealer, deactivated, or otherwise accounted for. Keep the valuation, the transfer log, and sale records with the rest of the estate paperwork.
Consignment usually takes weeks to a few months, depending on the firearms and demand. If a collection feels like too much to sort through alone, start with the inventory and the valuation — the selling decisions get much clearer from there.
