The Kosoff Award is given to a PNG member-dealer who has shown steadfast dedication to the entire numismatic community and who has made a significant contribution to the Guild or to the numismatic fraternity. The award is named after PNG’s Founding President who spearheaded the launch of the organization and served as its first President in 1954.

Halperin became a coin dealer as a teenager. In 1982 he partnered with Steve Ivy (PNG President from 2003 to 2005) to form what is now Heritage Auctions, the world’s largest rare coin and collectibles auction firm. In 1984, Halperin became a leading pioneer in standardized coin grading with the creation of NCI, the Numismatic Certification Institute, the first privately owned collectibles grading service. He has been a member of PNG for 35 years.

The Kosoff Award and other honors were announced and presented following the PNG Day activities prior to the 2025 Central States Numismatic Society Convention in the Chicago suburb of Schaumburg, Illinois.

These are the other PNG award winners honored at the dinner.
