Key Takeaways:
- Miller's Mint has operated in Patchogue, New York since 1967 and sells U.S. coins, world coins, paper money, and bullion both online and in-store.
- Gold traded near $4,050 per ounce and silver near $59 per ounce in early August 2026, both down roughly 27-28% from their January 2026 peaks, a swing that affects how any dealer prices physical metal.
- Customer reviews across Yelp, Birdeye, and BBB channels are largely positive, with recurring praise for fair appraisals and low-pressure buying, though the website inventory doesn't always match in-store stock.
Company Background
Harry Miller has worked as a professional numismatic dealer for more than 50 years. He holds a lifetime membership in the American Numismatic Association, belongs to the American Stamp Dealers Association, and previously chaired the Industry Council for Tangible Assets.
Those credentials matter in a field where pricing and grading disputes are common and where a buyer often has no independent way to verify a coin's condition before paying for it.
Miller is also a Marine Corps veteran and sits on the board of Gift of Life, a nonprofit that funds heart procedures for children overseas, which the company mentions on its About page as part of its community involvement.
The business is not BBB accredited, but it has an open BBB file dating back to February 1974, and its listing shows no unresolved complaint pattern.
On Birdeye, Miller's Mint carries a 4.8-star rating across 218 aggregated reviews. Yelp and Google reviewers repeatedly name a staff member, Matt, for handling appraisals and mail-in sales without pressuring customers to accept a lowball offer.
One reviewer described selling an inherited coin and paper money collection entirely through the mail and called the process straightforward.

What Miller's Mint Sells
The catalog splits into four main categories:
| Category | Examples Found on Site |
|---|---|
| U.S. Coins | Walking Liberty half dollars, Buffalo nickels, Morgan silver dollars, Draped Bust and Capped Bust half dollars, early gold half eagles and double eagles |
| World Coins | German states silver marks, French francs, Italian lire, Australian and Isle of Man gold proof issues, Puerto Rican and Danzig silver |
| U.S. Paper Money | Historical American currency, sorted by denomination and series |
| World Paper Money | Foreign banknotes across multiple eras and countries |
Inventory ranges from low-grade circulated coins priced for beginning collectors to certified, slabbed pieces graded by PCGS or NGC that run into the thousands of dollars.
A 1901 Morgan Silver Dollar graded MS-62 by PCGS and an 1803/2 Heraldic Half Eagle graded EF45 both showed up in current listings, alongside common-date Buffalo nickels that cost far less. This spread lets the site serve both a first-time buyer picking up a single coin and a serious collector chasing a specific date and mint mark.
Miller's Mint also buys coins, currency, bullion, and stamps, and offers free in-store evaluations along with appraisals for estates, insurance claims, and legal matters. That buy-side business appears significant, based on how often reviewers mention selling rather than buying.
Pricing and the Current Metals Market
Every dealer's coin and bullion prices move with the spot market, and 2026 has been an unusually volatile year for that market. Gold set an intraday record of roughly $5,590 to $5,600 per ounce on January 28, 2026, driven by heavy central bank buying and a wave of investment demand.
The World Gold Council reported that investors bought 2,175 tons of gold through ETFs, bars, and coins in 2025, an 84% jump from the prior year. Silver hit its own record above $116 per ounce the same week.
Since that January peak, both metals have pulled back sharply. As of early August 2026, gold was trading around $4,050 per ounce, about 27-28% below its record.
Silver sat near $59 per ounce, also well off its high. J.P. Morgan's Global Research team has forecast gold averaging closer to $6,000 per ounce by the end of 2026, though other analysts, including SD Bullion's James Anderson, expect prices to stay in a $3,900-$4,350 range through August before any rebound.
This matters for anyone reading a Miller's Mint listing today. The site itself warns that all prices shown are subject to change and get adjusted on final invoice based on current metal prices, which is standard practice for any physical bullion or numismatic dealer working with a live spot market.
A buyer comparing Miller's Mint against a large online bullion seller should check the spot price at the moment of purchase rather than relying on a cached product page, since gold has moved more than $1,500 per ounce in either direction within the past seven months.
Shipping, Payment, and Buying Process
Miller's Mint offers free shipping on orders over $500 and lists a phone number, 631-475-5353, for direct contact alongside the standard online checkout.
The company operates its retail store four days a week (Monday, Wednesday, Friday, and Saturday) and attends roughly 15 coin shows a year, giving buyers who prefer face-to-face transactions a way to inspect coins before paying.
One Birdeye reviewer noted that a website order for a single coin turned out to be out of stock and was refunded quickly, but flagged that shipping costs ran higher than what large marketplace sellers charge for a single low-value coin.
That same reviewer added that the coins themselves arrived in better condition than comparable listings found on Amazon, where cleaned or culled coins are common.
Grading and Verification
A recurring theme in the reviews is that Miller's Mint explains its pricing rather than just quoting a number. One customer selling a collection wrote that they were walked through the reasoning behind the offer on each item instead of receiving a flat take-it-or-leave-it price.
That matters more in coins than in most collectibles categories, because two coins of the same date and denomination can be worth wildly different amounts depending on wear, strike quality, and whether a third-party service like PCGS or NGC has certified the grade.
Several of the higher-value listings on the site, including the Morgan Silver Dollar and the Isle of Man gold proof coin, carry third-party grading, which removes some of the guesswork for a buyer who isn't trained to grade coins by eye.
Lower-value circulated coins, like the common Buffalo nickels in the current inventory, are typically sold raw (ungraded) with a condition description such as VF30 or EF40 assigned by staff.
For sellers, that same grading knowledge cuts the other way. The negative feedback found in reviews tends to center on individual staff interactions rather than pricing disputes. One reviewer described a younger employee as short-tempered while still praising Harry Miller directly.

How It Compares to Larger Dealers
Against national bullion retailers, Miller's Mint is smaller and more specialized. It doesn't carry the bulk-bar and modern mint-coin volume that a company built purely around bullion sales does.
What it offers instead is a numismatic specialty: graded rare coins, foreign issues, and paper money that require someone with grading expertise to source and price correctly.
Harry Miller's decades in the industry, including work as a Senior US Market & Pricing Analyst, are the reason customers cite for trusting the store's appraisals over a faceless online-only competitor.
For someone selling an inherited collection or looking for a specific date-and-mintmark coin rather than generic bullion, that specialization is the practical difference.
Conclusion
Miller's Mint operates as a long-standing, family-run numismatic dealer with a track record that outside reviews back up, particularly for selling and appraisal work.
Anyone buying or selling should check live gold and silver spot prices first, since both metals have swung by double-digit percentages since January 2026 and that volatility flows directly into every quote the store gives.
