A Grand Rapids-based entrepreneur — Richard Colonna of Quantitative Collectors Group (QCG) — has developed a first-of-its-kind device designed to transform how coin collectors grade and value their currency.
The OCS200 introduces a technology-driven approach that removes subjectivity from coin grading — making it faster, more consistent, and more accessible, according to the inventor.
Developed by a team of experts in manufacturing, technology hardware, and software, QCG’s technology is a shift from the traditional grading process, which depends on individual interpretation, often resulting in different grades based on who is reviewing the coins.
For generations, coin grading has relied on a handful of third-party graders. Collectors mail their coins away, wait weeks, and receive a subjective Sheldon Grade, which varies depending on the grader’s opinion.
QCG changes that paradigm with the OCS200, an IoT-based digital microscope that uses precision internal lighting and high-resolution imaging to analyze coins across five key grading areas: wear, surface preservation, luster, strike, and eye appeal.
Once scanned, QCG’s software generates a detailed report in less than 15 minutes, emailed directly to the user. Each report includes the coin’s unique digital fingerprint, featuring a Quantitative Sheldon Grade and current market value based on Greysheet data — a wholesale price guide for rare coins and currency.
“QCG isn’t here to disrupt the art of coin collecting; it’s here to make coin grading trustworthy, accessible, and affordable for all collectors,” says Colonna, founder of QCG. “Today, traditional coin grading depends heavily on subjective expertise, while QCG introduces a quantitative approach using scientific instrumentation to support and complement that process.
“Using a mixed-method approach of quantitative analysis and subjective interpretation in coin grading encourages greater confidence and clarity for each coin grade.”
The QCG team brings together decades of experience in manufacturing, software development, and optical technology. Their shared mission: to take the guesswork out of coin grading and build a more transparent, trustworthy standard for collectors worldwide.
“Each scan not only provides valuable, transparent, and visual insight,” Colonna says, “but also contributes to a worldwide network of consistent coin evaluations — strengthening trust and accessibility across the hobby.”
QCG’s OCS200 will be available for early supporters through a crowdfunding campaign on Indiegogo.com beginning in January 2026. Each pledge of $775 — a 61 percent discount off the projected retail price of $1,995 — includes the QCG device and 50 free coin scans. This Michigan-made innovation allows collectors everywhere to grade smarter, faster, and more affordably — all from the comfort of home.
