2024 Denver Show Auction - Jack Halpern Collection!

We are truly honored to give you a first release to our auctions of significant specimens from the recent acquisition of the collection of our friend and legendary collector, Jack Halpern (https://www.irocks.com/the-jack-halpern-collection). At 104 years old, he has decided to let the remaining collection of 2000 pieces go to new homes, and eagerly awaits us telling him how many countries and cities these will go out to! We have never purchased a major Big Ten collection with the goal of auctioning 90 percent or more of it (nobody has!); but that is what we will do over the years ahead, to share this with the community. Stay tuned!
