Whether you’re settling an estate, liquidating an inherited gun collection, or insuring antique firearms, we can help you understand what your firearms are worth and what steps to take next.
Many clients prefer working with us because we can often handle much of the process remotely or come to you directly, helping avoid unnecessary transportation or handling of firearms you may not feel comfortable managing.

Appraisal Experience
Evaluating Historic & Collector Firearms
Because firearms are often passed down through generations, many collections include antique, historic, or collector firearms that require more detailed evaluation. Factors such as condition, originality, manufacturer markings, production variations, historical significance, and current collector demand can all influence value.
CGS has evaluated collections containing antique revolvers, military surplus rifles, collectible shotguns, discontinued models, and historically significant firearms where proper identification and documentation were especially important.
This experience helps clients better understand not just what a firearm may be worth, but why certain pieces may carry additional collector, historical, or market value.
Clear. Professional. Safe
Our Gun Appraisal Process
We make the firearm appraisal process clear and straightforward, guiding you through each step from initial review to final documentation.
Reach Out
Contact us to discuss your firearms and why you’re seeking an appraisal. Once we understand your situation, we’ll recommend either an online or on-site appraisal and coordinate the next steps.
Inspection
We inspect and document key details of each firearm. This includes serial numbers, manufacturer markings, make/model, and overall condition.
Research
We research each piece to verify when and where it was manufactured, along with any historical relevance or documented provenance. This helps establish authenticity and overall market value.
Valuation
We determine fair market value by researching recent sales of comparable firearms through national auction sites and other trusted market sources. This allows us to provide an accurate, data-backed valuation for each firearm.
Report
You’ll receive an official appraisal report documenting the details, research, and valuation of each firearm in the collection.
Trusted by Families, Executors, Attorneys & Estate Professionals
Our appraisals provide clear documentation and accurate valuations for estate administration, probate, trusts, liquidation, and insurance.
