A $15,000 Gun Collection Doesn't Mean You'll Receive $15,000: FMV vs. MCV Explained

Oct 7
4 min read

Someone tells you your firearm collection is worth $15,000, then a dealer or professional buyer looks at the same collection and offers $10,000. Does that mean the collection was overvalued? Is the buyer making an unfair offer?


Not necessarily, the two numbers may be answering different questions.


For someone who has inherited firearms, is downsizing a collection, or is considering selling, understanding the difference between Fair Market Value (FMV) and Marketable Cash Value (MCV) can help explain why a collection's market value may differ from the amount an owner can reasonably expect to receive when converting it to cash.


What Is Fair Market Value (FMV)?

Fair Market Value helps answer:

“What is this property worth in the appropriate market?”

FMV may be important for an estate, probate matter, divorce, insurance, tax purpose, or another situation requiring a formal valuation.


But FMV does not automatically answer:

“How much cash can I receive for the entire collection today?”

A firearm can have an FMV of $1,000 without a dealer being able to pay the owner $1,000 and economically resell it.

That is where another value concept becomes useful.


What Is Marketable Cash Value (MCV)?

Marketable Cash Value considers the realities of converting property into cash.


Marketable Cash Value (MCV) considers more than a firearm collection’s market value. Demand, condition, selling costs, time to cash, method of sale, and the size and composition of the collection can all affect what an owner may reasonably receive.
Marketable Cash Value (MCV) considers more than a firearm collection’s market value. Demand, condition, selling costs, time to cash, method of sale, and the size and composition of the collection can all affect what an owner may reasonably receive.

In simple terms:

  • FMV helps describe what the property is worth in the market.

  • MCV helps describe what the property may reasonably produce when converted into cash under the relevant market conditions.


The two numbers should not automatically be expected to be the same.


A Simple $15,000 Collection Example

Suppose a 20-gun collection has an estimated FMV of $15,000, that does not necessarily mean the owner should expect a $15,000 cash offer.


An auction or consignment may produce a gross selling price approaching—or sometimes exceeding—the expected market value. But Seller commissions and other applicable costs can reduce what the owner ultimately receives. That final amount is the seller net.


The important question is not simply:

“Why is the offer lower than $15,000?”

It is:

“What does each number represent, and what will I actually receive under each option?”

Why Doesn't a Dealer Pay Full FMV?

A dealer buying a firearm is not the final retail buyer.


The dealer must invest capital in the property, prepare and market it, find another buyer, complete the eventual transaction and accept the possibility that the firearm may take longer to sell or sell for less than anticipated.


There must also be enough margin for the transaction to make economic sense. That doesn't automatically make a lower offer fair. It simply explains why dealer acquisition price and Fair Market Value are different concepts.


There Is No Universal “Fair Percentage”


This is where rules such as:

“Dealers should pay 70% of value.”

can become misleading.


Consider two firearms that each have an FMV of $1,000. One might be highly desirable and sell quickly. The other may have limited demand and take months to find the right buyer.


They can have similar FMVs while having very different marketability. Across a collection of 20, 30 or 50 firearms, those differences become even more significant.


That's why MDRF evaluates collections item by item as well as collectively, rather than applying one predetermined percentage to every firearm.


FMV, MCV and Seller Net Are Not the Same Thing

An owner considering a sale may encounter several different numbers:


Fair Market Value, Marketable Cash Value, auction hammer price, seller net and a direct purchase offer each answer a different question. Understanding the difference helps owners compare what a firearm collection is worth with what they may actually receive.
Fair Market Value, Marketable Cash Value, auction hammer price, seller net and a direct purchase offer each answer a different question. Understanding the difference helps owners compare what a firearm collection is worth with what they may actually receive.

These numbers are related, but they are not interchangeable.


That is why comparing a $15,000 FMV directly with a $10,000 cash offer doesn't necessarily tell you whether the offer is fair.


Don't Forget the Rest of the Collection

The value may also extend beyond the firearms themselves.


Original boxes, manuals, factory accessories, optics, magazines, ammunition, reloading equipment, knives and provenance documentation can have value of their own or affect the desirability of particular firearms.


Before evaluating an offer, make sure you understand exactly what property is included.

An offer for the firearms alone is not necessarily comparable with an offer that also includes ammunition, optics and other associated property.


So How Do You Know Whether an Offer Is Fair?

Instead of focusing only on the percentage of FMV being offered, consider:

  • What is the collection actually worth?

  • What would you likely net through another selling method?

  • How long will it take to receive the money?

  • What costs, work and uncertainty are involved?


Then compare those expected outcomes with the direct offer.


A direct sale can provide immediate payment, certainty and simplicity. An auction may provide more upside for the right firearm but require additional time. Selling individually may produce another result while requiring substantially more work.


There is no single answer for every collection.


Understand the Value Before You Decide

MDRF Enterprises distinguishes between a formal certified appraisal and a collection evaluation because they serve different purposes.


A certified appraisal may be appropriate when an independent formal valuation is required for probate, court, insurance, tax, divorce or another defined purpose.


A collection evaluation may be more appropriate when the goal is understanding what a collection contains, its FMV and MCV, and the owner's options before a potential sale.


So if someone tells you your firearm collection is worth $15,000, the next question shouldn't automatically be:

“Why won't someone give me $15,000?”

A better question is:

“What does that $15,000 represent, and what can I reasonably expect to receive under each of my options?”
