  • I started taking coin photos in 1996 at RARCOA with a Polaroid 2000. While the photos were pretty terrible by today’s standards, they were ahead of the game at that time.

  • At 1000 guesses, and still holding at 70%+. I still believe that 75% will be a tough score to top at 1000+ guesses. We have some 70%+ players at the top of the leader board, but their scores will likely drop over time. I'm getting great at grading Roosevelt Dimes and Washington Quarters, and a lot of old brain cells are waking up. I hoping to better my score by 1 or 2 % over the next 1000 guesses.

  • Be careful, as Guess the Grade could be a new addiction. I've been playing with this today prior to the official launch, and after grading 400 coins today - more correctly 400 pictures of coins - I have a few tips for all of you that want to give it a try ...

    Use your plusses - If you are not sure about a 63 or 64 grade, 63+ will only cost you a two point deduction instead of the eight point deduction if you are one full grade off.

    Don't forget about that BN suffix, as I believe that I lost two points on some circulated Indian Cents for not noting the BN.

    I tried grading faster, at a pace of about 15 seconds per coin, and started slipping in my results. Slowing down just a touch and my results improved. My suggestion is that you take a little bit of extra time but develop a pace. After a couple of hundred coins you should hit a groove.

    Grading coins from photos can be tough, especially for proofs. I expect that a 75% accuracy will prove to be a top score over a large sample. I'm hoping to work my score back over 70%.

    Finally, remember that this is a game.

  • 1795 Flowing Hair 50c, O.123 .... For now, much should the reverse adjustment reduce the grade, if any?
