Inherited a 1705 Brunswick-Lüneburg 2/3 Thaler? What You Need to Know Before Selling

If you inherited this piece, your first instinct might be to take it to a local pawn shop. I get it — when you’re overwhelmed by an estate, convenience feels like a lifeline. But here’s how to properly assess what you’ve got so you don’t leave serious money on the table.

As an estate liquidator who has handled hundreds of inherited coin collections, I can tell you from experience: the difference between a quick pawn shop sale and a properly managed auction can mean hundreds — sometimes thousands — of dollars. A coin like the 1705 Brunswick-Lüneburg-Celle 2/3 Thaler is a perfect example of a piece that deserves careful handling. It carries genuine historical significance, a well-documented numismatic reference, and a collector market that rewards patience and expertise.

In this guide, I’ll walk you through everything you need to know: how to identify and document the coin properly, how inheritance tax might apply to your situation, why a professional appraisal is absolutely essential, how to steer clear of scams, and — most importantly — how to find the right auction house to maximize your return.

Identifying Your Inherited Coin: The 1705 Brunswick-Lüneburg-Celle 2/3 Thaler

Before you can sell or appraise any inherited coin, you need to know exactly what you’re holding. In this case, the coin in question is a 1705, 2/3 Thaler from Brunswick-Lüneburg-Celle, catalogued as KM#17 in the Krause-Mishler standard reference. The specific variety is referenced as Welter 2153 — and that’s the search term you should use when digging through comparable auction results.

Here are the key identification markers to confirm on your piece:

• Date: 1705 (part of the 1698–1705 series)
• Denomination: 2/3 Thaler (also known as a “Gulden” or “Gulden-Thaler” in some references)
• State: Brunswick-Lüneburg-Celle (a subdivision of the broader Brunswick-Lüneburg-Calenberg-Hannover complex)
• KM Number: KM#17
• Welter Reference: Welter 2153
• Ruler: George Ludwig (the future King George I of Great Britain)

The obverse typically features a portrait of George Ludwig, while the reverse displays the arms of Brunswick-Lüneburg. Confirming the exact variety is critical here — values can differ significantly between dates and mints within the same series. A rare variety in this range can command a substantial premium over a common date, so don’t gloss over the details.

The Historical Significance: George Ludwig and the British Succession

One of the most fascinating aspects of this coin — and something that genuinely excites collectors — is its direct connection to British royal history. The “George Ludwig” depicted on the obverse would eventually become King George I of Great Britain. In 1705, he was still the Duke of Brunswick-Lüneburg. He wouldn’t even become Elector of Hanover until later. When Queen Anne died in 1714 without surviving children, George Ludwig ascended to the British throne as the nearest Protestant heir, being the great-grandson of James I.

This historical narrative adds a layer of collectibility that goes well beyond the coin’s metal content or even its numismatic rarity. Coins with direct ties to the British Hanoverian succession are actively sought by collectors of both German States coinage and British royal memorabilia. When you present this coin to an auction house, make sure to highlight this connection. I’ve seen it meaningfully increase buyer interest — and ultimately, the hammer price.

Inheritance Tax: What You Need to Know

One of the first questions I get from families handling an estate is: “Do we owe taxes on this coin?” It’s a fair question, and the answer depends on your jurisdiction. But here are the general principles that apply in most cases.

Fair Market Value and the Estate Tax Basis

In the United States, inherited property — including coins — generally receives a “stepped-up basis” to its fair market value (FMV) as of the date of the decedent’s death. Let me put that in plain English: if your grandfather bought this coin decades ago for a few dollars and it’s now worth $120, your cost basis for capital gains purposes is $120, not the original purchase price. If you sell it immediately for $120, you may owe little to no capital gains tax.

However, if the total value of the estate exceeds the federal exemption threshold — currently over $12 million for an individual, though this figure is subject to legislative change — the estate itself may be subject to federal estate tax. Many states also have their own estate or inheritance tax thresholds, which can be significantly lower than the federal level.

Key takeaway: You need a professional appraisal to establish the FMV of the coin as of the date of death. This appraisal serves double duty — it satisfies IRS requirements and gives you a realistic baseline for selling.

State Inheritance Tax Considerations

Some states impose an inheritance tax — distinct from an estate tax — on the beneficiaries who receive property. The rate often depends on your relationship to the decedent. Spouses are typically exempt, while more distant relatives or non-relatives may face higher rates. Check with a tax professional in your state to understand your specific obligations. It’s not worth guessing on this.

Why a Professional Appraisal Is Non-Negotiable

I cannot stress this enough: do not rely on a 1997 Krause catalogue or a single online price guide to determine the value of your inherited coin. I’ve seen forum discussions referencing a 1997 Krause listing of $90 in VF condition — but that was nearly 30 years ago. Markets change. Collector preferences shift. Condition assessments evolve. The numismatic value of a piece today reflects a completely different landscape.

What a Professional Appraisal Includes

A qualified numismatic appraiser will provide:

1. Accurate identification of the coin, including date, mint, variety, and reference numbers (KM#17, Welter 2153)
2. Condition grading using the standard Sheldon scale (e.g., VF-20, VF-30, XF-40) — this is where eye appeal, luster, and strike quality all factor into the final assessment
3. Fair market value based on recent comparable sales, not outdated catalogue prices
4. A written report suitable for insurance, estate tax, or legal purposes
5. Authentication confirming the coin is genuine and not a counterfeit or altered piece

For a coin like the 1705 Brunswick-Lüneburg 2/3 Thaler, recent auction data suggests pieces in similar grade have sold for approximately 100€ (roughly $120 USD) at auction, before buyer’s premiums. With typical auction fees of around 20%, the net to the seller would be closer to $96–$100. That’s a meaningful difference from the gross hammer price, and it’s exactly the kind of detail an appraiser will help you understand before you commit to anything.

Where to Find a Qualified Appraiser

Look for appraisers affiliated with recognized organizations such as:

• American Numismatic Association (ANA) — certified appraisers
• American Society of Appraisers (ASA) — accredited members with numismatic specializations
• International Society of Appraisers (ISA) — personal property appraisers
• PCGS or NGC — while primarily grading services, they can direct you to reputable appraisers

Here’s a rule I live by: avoid appraisers who offer to both appraise and purchase the coin from you. That’s a conflict of interest and a common setup for undervaluation scams. Period.

Avoiding Scams: Protecting Yourself and the Estate

Inherited coins are a prime target for unscrupulous buyers. As an estate liquidator, I’ve seen families lose significant value because they didn’t know the warning signs. Let me share what I’ve learned so you don’t repeat those mistakes.

Red Flags to Watch For

• “We’ll give you cash today” — Legitimate dealers and auction houses don’t pressure you into immediate decisions. Anyone offering instant cash for an inherited collection is almost certainly lowballing you. Walk away.
• No written offer — Any serious buyer will provide a written offer with specific prices for specific coins. Verbal offers are meaningless and tend to evaporate the moment you ask for documentation.
• Offers based on “melt value” only — A 2/3 Thaler contains silver, but its numismatic value far exceeds its melt value. Anyone offering only melt value is deliberately ignoring the coin’s collectible premium.
• Unsolicited contact — If someone contacts you after seeing an obituary or estate sale listing, be extremely cautious. This is a common tactic used by predatory buyers who prey on grieving families.
• Refusal to let you get a second opinion — A legitimate buyer will never object to you seeking an independent appraisal. If they do, that tells you everything you need to know.

The Pawn Shop Trap

I understand the temptation. A local pawn shop is convenient, and they’ll put cash in your hand on the spot. But pawn shops are in the business of buying low and selling high. For a coin like the 1705 Brunswick-Lüneburg 2/3 Thaler, a pawn shop might offer $30–$50 — a fraction of its true market value. The convenience is simply not worth the loss.

Take the time to get a professional appraisal and explore the options I’m outlining below. The difference in your net proceeds can be dramatic, and your family deserves better than a fire sale.

Finding the Right Auction House

Not all auction houses are created equal, and choosing the right one can make a significant difference in your final return. Here’s how to evaluate your options with a critical eye.

Specialist vs. General Auction Houses

For a coin like the 1705 Brunswick-Lüneburg 2/3 Thaler, you have two main paths:

1. Specialist numismatic auction houses — These firms focus exclusively on coins and currency. They have dedicated collector bases, detailed cataloguing expertise, and the ability to highlight the historical significance of your piece. Examples include Heritage Auctions, Stack’s Bowers, Künzen und Münzen (for German States material), and Baldwin’s.
2. General auction houses with coin departments — Larger firms like Sotheby’s, Christie’s, or regional auction houses may handle coins as part of broader estate sales. This can work well if your coin is part of a larger collection, but a single coin might not receive the focused attention it deserves.

For a single coin or small collection, I generally recommend a specialist numismatic auction house. They understand the nuances of German States coinage, they know which collectors are actively buying, and they can properly attribute varieties like Welter 2153 — which directly impacts the final price.

Questions to Ask Before Consigning

Before you commit to an auction house, ask these questions — and get the answers in writing:

• What is the buyer’s premium? — This is the fee charged to the buyer on top of the hammer price. Typical rates are 18–25%. While this doesn’t come out of your pocket directly, a high buyer’s premium can suppress bidding.
• What is the seller’s commission? — Many specialist auction houses charge the seller 0–15% of the hammer price. Some offer 0% seller’s commission as an incentive. Negotiate this — it’s not always set in stone.
• How will the coin be catalogued? — A good auction house will provide a detailed description, including the KM number, Welter reference, grade, and historical context. The George I connection should be prominently highlighted — provenance and story matter to collectors.
• What is the estimated value range? — A reputable house will give you a realistic estimate, not an inflated number designed to win your consignment. Be wary of anyone who promises the moon.
• What is the timeline? — Understand when the auction will take place, when you’ll receive payment, and what happens if the coin doesn’t sell.
• Do you offer a reserve price option? — A reserve price ensures the coin won’t sell below a minimum threshold. This protects you from a lowball result in a weak market.

Online Auction Platforms

Don’t overlook online platforms entirely. eBay, MA-Shards, and specialized numismatic platforms can be effective for coins in this price range. However, you’ll need to handle photography, description, grading, and shipping yourself — and you’ll need to be confident in your ability to authenticate and present the coin accurately. For most inheritors, I recommend letting a professional auction house handle the sale. The peace of mind alone is worth it.

Documenting and Preserving the Coin Before Sale

While you’re going through the appraisal and auction house selection process, take steps to preserve the coin’s condition and document its history. This is where many inheritors accidentally destroy value without realizing it.

Handling and Storage

• Never clean the coin. I cannot say this loudly enough. Cleaning — even gentle cleaning — can destroy the natural surface patina and reduce the coin’s value dramatically. That aged toning and luster are part of what makes the piece desirable. Leave it alone.
• Handle by the edges only. Fingerprints contain oils that can damage the surface over time. It takes two seconds to pick up a coin the right way.
• Store in a proper holder. Use a Mylar flip, a hard plastic capsule, or a coin envelope designed for long-term storage. Avoid PVC-containing soft plastic holders — PVC can cause irreversible damage that shows up years later.
• Keep the coin in a stable environment. Avoid extreme temperatures, high humidity, and direct sunlight. A simple drawer at room temperature works fine.

Provenance Documentation

If you have any documentation about how the coin was acquired — previous owner’s records, a family letter, a prior appraisal, even a handwritten note — keep it with the coin. Provenance can add real value, especially for coins with historical significance. Even something as simple as “Grandfather’s collection, acquired in the 1960s” can be meaningful to future collectors. It connects the object to a human story, and that matters more than most people realize.

Putting It All Together: A Step-by-Step Action Plan

Here’s a summary of the steps I recommend for anyone who has inherited a coin like the 1705 Brunswick-Lüneburg 2/3 Thaler. Follow this sequence and you’ll be in a strong position:

1. Identify the coin. Confirm the date, denomination, state, KM number, and variety reference. Use online resources like the NGC Price Guide (search KM#17 for German States Brunswick-Lüneburg-Calenberg-Hannover 2/3 Thaler) and auction archives. Don’t skip this step — accurate identification is everything.
2. Research recent sales. Search for “Welter 2153” or “KM#17” in completed auction lots to understand current market values. Remember to account for buyer’s premiums when comparing prices. A coin that “sold for $120” might only have netted the seller $96.
3. Get a professional appraisal. Hire a qualified, independent appraiser who has no interest in purchasing the coin. Obtain a written report for tax and estate purposes. This is your foundation.
4. Understand your tax obligations. Consult with a tax professional about estate tax, inheritance tax, and capital gains implications in your jurisdiction. Don’t guess on this — the penalties for getting it wrong aren’t worth the risk.
5. Choose the right sales channel. For a coin of this nature and value, a specialist numismatic auction house is typically the best option. Compare commissions, cataloguing quality, and timelines before committing.
6. Preserve the coin. Store it properly, don’t clean it under any circumstances, and keep any provenance documentation with it. Protect the condition and the story.
7. Be patient. This is the hardest part. The difference between a quick sale and a properly managed sale can be 2–5x the return. Take the time to do it right.

Conclusion: A Small Coin with a Big Story

The 1705 Brunswick-Lüneburg-Celle 2/3 Thaler is more than just a piece of silver. It’s a tangible link to one of the most consequential transitions in British royal history — the Hanoverian succession that brought George I to the throne and shaped the course of the British Empire. For collectors of German States coinage, British royal memorabilia, or early 18th-century European history, this is a genuinely desirable piece with real collectibility.

With a current market value in the range of $100–$120 at auction (before fees), it may not be a fortune — but it’s far more than a pawn shop would offer, and it deserves to be handled with the care and expertise that reflects its historical importance. If you’ve inherited a coin like this, take the time to get it properly appraised, understand your tax obligations, and find the right auction house. Your grandfather’s collection — and the history it represents — is worth the effort.

As always, if you have questions about an inherited coin or need help navigating the estate liquidation process, don’t hesitate to reach out to a qualified numismatic professional. The right guidance can make all the difference — and you’ll never regret doing it the right way.
