Leading numismatist in Austin, TX.

Powell Coins is a distinguished numismatic firm founded by Grant Powell, whose lifelong passion for coins began in childhood and evolved into a deeply informed practice of collecting, scholarship, and dealing. Built on decades of study and hands-on experience, Powell Coins is recognized for its focus on historically significant, museum-quality material and a disciplined, provenance-driven approach to numismatics.

While Grant Powell’s collecting roots extend back many years, the firm officially went to market as an online-only dealer in 2020 during the COVID era. In its first few years of operation alone, Powell Coins successfully placed over $3 million in rare coins, a testament to both the quality of its material and the trust it has earned within the global numismatic community.

The firm is particularly noted for its holdings in rare gold and silver coinage spanning the 11th through 19th centuries, with an emphasis on exceptional preservation, rarity, and historical context. Powell Coins has assembled and placed some of the finest examples from medieval and early modern periods, appealing to advanced collectors who value both aesthetic excellence and scholarly importance.

Among its most significant achievements, Powell Coins curated one of the most important collections of rare historical Scottish coinage to come to market in the past decade. This landmark collection was presented by Heritage Auctions in January 2026, marking a notable event in the field and reaffirming the firm’s reputation for sourcing and stewarding world-class material.

In addition to its strengths in European coinage, Powell Coins is an active dealer in rare United States coins and historic bank notes, applying the same rigorous standards of authenticity, condition, and historical relevance. At its core, Powell Coins exists to preserve and place tangible pieces of history—connecting collectors with artifacts that tell enduring stories of commerce, power, and culture across centuries.
