The Current Coin Grading Experience
The current coin grading experience requires collectors to send their coins to a third-party grading service for manual inspection by grading experts. This process includes a complicated entry form, variable fees (depending on the age and value of the coin), shipping, and waiting for a response.
A Detailed FingerPrint Grading Report in 15 Minutes or Less
QCG provides detailed coin measurements, bringing greater transparency to grading.
We measure eight elements: strike, luster, balance, wear, spots, toning, surface, and eye appeal. Your FingerPrint Report includes images, analytics, a quantitative Sheldon Grade, and estimated market value—delivered within 5–10 minutes after scanning.
Computer Coin Grading Measurements
Effective hard data measurements must satisfy three specific baseline quality dimensions:
(1) Objectivity: The measurement stays identical regardless of who performs the test.
(2) Verifiable: The same measurement process must arrive at the same number.
(3) Reliability: The data captured is via structured and calibrated machinery.
Using Advanced Image Analysis to Determine a Sheldon Grade
Image capture takes place in a light-tight chamber with four light sources, capturing at least 24 images per coin.
This video shows the machine’s internal process. The on-screen interface is embedded software that captures and analyzes images for grading. During normal use, simply insert your coin, start the scan, and receive your computer-generated grading report.
Computer Coin Grading Machine vs. Cell Phone App Photos
There is significant hardware-driven bias in cell phone cameras and lenses, primarily driven by the physical limitations of fitting high-quality optics into thin, mobile devices. Taking a photo of a coin with your cell phone is not only limited by the phone hardware, but it is also significantly impacted by the environment where you take the photos.
The OCS200 CoinGradr controls all aspects of the photo-taking environment from illumination intensity sensor to light-tight enclosure that uses industrial-grade imaging technology to capture the highest level of detail possible. This all leads to better images, more accurate analysis, and more consistent grading outcomes.
