How Much Is a COP Derringer Worth? (2026 Value Update)

How We Calculate Used COP Derringer Values

COP Derringer value depends mainly on its condition and accessories or upgrades.

Variant and finish don’t affect it much because there was only one option for both.

Condition and Values

COP Derringers tend to be treated as collectible guns, not duty ones. As such, condition has a massive effect on their valuation.

To get the condition grade of your Derringer, have it appraised by a professional. This may involve a fee. However, we provide free gun appraisal online if you’re selling firearms to us.

To see how we professionally evaluate your firearm (for free) and turn that condition into a payout, view our 3-step selling process for a guaranteed FFL offer.

After that, you can use the key below to figure out the answer to “How much is my COP Derringer worth.”

How Accessories Affect What We Pay for Your Derringer

Some accessories can improve the value of a gun, especially a collectible one. That being said, you should remember that some buyers won’t be interested in what they see as an “extra.”

If you can’t find someone who’ll pay for both the gun and the accessories you’re selling, contact us. We often make offers on everything, from accessories to ammunition.

Original Box and Papers

The COP Derringer came with some nice, distinctive packaging. If you have the original silver-trimmed blue box with the crushed blue velvet inside, you can often sell it with the gun.

As with most other things for collectibles, expect more if the box and papers are in excellent condition.

Value: Around $15 to $40 for the matching box and papers.

Derringer Holster

Most people don’t actually want to carry the Derringer, so you may have some trouble trying to sell this. Better holsters in superb condition will obviously be easier to move as well.

You’re less likely to find someone interested in a nylon holster vs. a handcrafted leather one, for example.

Value: Around 20% to 40% for the accessory’s original value.
