Good luck, same rules as last time!

I thought it would be interesting to run a sort of experiment here with GTGs. Oftentimes posters will use GTGs to get an idea of if to resubmit a coin, or not to.

Here's my question - how accurate is the forum, grading from images alone? Over the years, I've built up a good chunk of coins with my own images that we can use for this purpose, given the consistent images and vast array of grades/services.

Here's how I plan to do it - one coin a week, after which the grades will be tallied and scored. Each correct answer will be 0 points, 1 point off is 1 point, 2 points off 2 points, etc. Missing designations counts as a point. Essentially, the fewer points at the end of the grade session the better. All coins for the moment will be CAC certified, so as to add another degree of accuracy in the actual grade. I will also choose coins I feel are properly graded.

I will upload the guesses into the below publicly accessible Google Sheet, so you all can view the data for yourselves.

I'll let each coin run for roughly three days.


Note - the white lines showing in the images are on the slab, not the coin.
