Our Story
The International Grading Agency was founded with a singular purpose: to bring world-class coin grading standards to collectors and dealers who deserve an independent, trusted authority for their numismatic treasures.
Recognizing the growing need for professional grading services that understand the nuances of Middle Eastern, North African, and international coinage, our founders assembled a team of expert numismatists with decades of combined experience in coin authentication and grading.
Our state-of-the-art facility combines traditional numismatic expertise with modern technology. Every coin submitted to IGA undergoes a rigorous multi-step process that includes authentication, grading, and encapsulation in tamper-evident holders. Our structured grading system eliminates subjectivity and ensures that every grade is reproducible and defensible.
Today, IGA serves a growing community of collectors, dealers, and auction houses who trust our grades and rely on our population data to make informed decisions. We continue to invest in our people, processes, and technology to maintain the highest standards in the industry.
