Technology has transformed almost every major industry since the 1990s, yet coin grading has heavily relied on the same subjective, human-driven processes for decades. As a numismatist, I’ve watched human factors like fatigue, personal preference, and market pressure introduce inconsistencies into third-party grading.
That is why I am incredibly excited to share that my feature article, "Computer Coin Grading: An Introduction," has just been published by the American Numismatic Association (ANA) Reading Room!
In this article, I dive deep into why early 90s attempts at computerized grading stalled, how modern computer vision has eliminated those old technical barriers, and why quantitative facts—not human emotions—are the key to true grading consistency.
Here is a quick look at what I discuss in the piece:
The article emphasizes that computers rely on quantitative measurements rather than opinions to consistently analyze contact marks, strike quality, and surface reflectivity without human emotion or fatigue. You can read the full, unedited quote and complete article in the referenced web document.
The piece also highlights hardware solutions like the OCS200 portable grading machine for fast results.
