Welcome to the Online Coin Grading Experiment

This experiment involves grading the obverse of coin images of 20 Lincoln Cents so that we can statistically compare your results against the other online graders and against the automated machine-based grading system.

Each coin image has been graded by our automated coin grading system and that grade will be provided to you for informational purposes for most of the coin images that you will see.
