Editor’s Note
Heritage Auctions Japan will host preview events for rare coins and luxury items in Osaka (October 3–4, 2025) and Tokyo (October 7, 2025). These events offer a unique opportunity for collectors and enthusiasts to view exceptional pieces ahead of upcoming auctions.
Heritage Auctions Japan (Headquarters: Texas, USA) will hold preview events for rare coins and luxury items at The Westin Osaka on October 3rd (Friday) and 4th (Saturday), 2025, and at Andaz Tokyo on October 7th (Tuesday), 2025.
The event will showcase notable items from upcoming coin, jewelry, watch, and handbag auctions scheduled from November 2025 to January 2026. Attendees can view additional Japanese and British antique coins from the “P Family Collection” and “Eternal Collection,” which gained attention at this summer’s coin auction, as well as rare items like a valuable pink diamond.
For this event, Chris Bierrenbach, an executive from the Coin Department, and Kyle Johnson, the newly appointed Director of the World & Ancient Coins Department, will travel from the US headquarters to Japan. They will host gallery talks introducing the displayed items and mini-lectures for coin beginners. Everyone is welcome to attend.
Heritage Auctions was founded in 1976 by coin collectors Steve Ivy and Jim Halperin and has been dealing in rare coins for over 45 years. As a result, it has established itself as the world’s largest auction house in the rare coin sector. Coins consigned from collectors worldwide, including the US, are often highly rare, and their value has increased further in recent years against the backdrop of rising gold prices. Collector interest in items like coins is growing yearly. In the first half of 2025, many items sold at Heritage Auctions achieved high prices, contributing significantly to the company’s record half-year total sales.
