If you’re thinking about selling a coin or stamp collection in New England, you’ve likely considered a few options—private sale, consignment, or visiting a local dealer. But there’s one method that consistently delivers better results for sellers of all experience levels: public auction. At Centennial Auctions, we’ve been helping individuals, families, attorneys, and estates sell collections for more than 30 years—and here’s why auctioning is the smartest route to take.
Auctions Create Demand Through Competition
Selling to a single buyer may seem convenient, but it rarely leads to the best price. An auction, on the other hand, creates a competitive environment where multiple buyers bid against each other, naturally pushing the price up. This is especially effective for rare or in-demand coins and stamps.
With our established base of serious collectors and dealers across New England and the U.S., Centennial Auctions ensures that your items receive the attention—and bidding—they deserve.
Real Market Value, Not Guesswork
How do you know what your collection is really worth? An auction removes the guesswork. Buyers determine the value through open bidding, so the final price reflects true market demand at that time.
Unlike selling to a dealer (who needs to buy low and sell high), an auction lets the market speak for itself. You’re not negotiating in the dark—you’re getting a fair, transparent sale in front of a live audience of qualified buyers.
We Market Your Collection to the Right People
Getting your collection in front of serious buyers is key to getting strong results. That’s where our decades of experience make a difference. Centennial Auctions promotes every event across multiple channels—from our own targeted buyer list to collector groups, online platforms, and printed catalogs.
That means more eyes on your coins and stamps, and more chances to get top-dollar offers.
A Streamlined, Stress-Free Process
Selling a collection on your own means researching prices, managing inquiries, negotiating deals, and handling transactions. That’s a lot to take on, especially if the collection isn’t something you’re familiar with.
With Centennial Auctions, we take care of everything—from appraising and cataloging your items to managing the bidding and ensuring prompt payment. For estates or inherited collections, we work directly with attorneys and executors to make the process efficient and accurate.
Reputation Matters—And Ours Is Proven
We’ve been the leading name in coin and stamp auctions in New England for decades, and we’ve earned our reputation through professionalism, results, and trust. Our appraisers are USPAP-compliant, ensuring ethical evaluations and documentation. Whether you’re a collector downsizing or a family managing an estate, you’re in good hands.
Local Expertise, National Reach
Though we’re rooted in New England, Centennial Auctions attracts national and even international bidders. Our auctions blend the personal attention of a local firm with the reach of a broader marketplace. That means more bidders, more competition, and better outcomes—no matter where your collection originates.
