Need Coin Collectors and/or Dealers to participate in Online Grading Test

rbassett · March 30, 2003 12:38PM

I am seeking coin collectors and/or coin dealers to take part in my online coin grading experiment. This experiment involves grading the obverse of 20 circulated Lincoln Cents from scanned computerized images. This experiment is very quick and easy to take, I modified it greatly based on the feedback received from the original test in January.

I am working on my doctorial dissertation in human and machine-based (computerized) grading of collectibles in the application area of coin grading. This dissertation will attempt to ascertain how well humans do at grading, how well computers do at grading and how successful collaborative human/machine grading may be.

Here is a link to the test site: http://www.rickbassett.com/pace/dissertation/new_test/coin.asp

Thank you for the consideration

Is it me or was seeing the computer grade posted distracting to you too.

I see how tireing it could be just grading coins all day.
Man I bet pro graders take alot of breaks.
I wonder how many coins a pro grader does grade before he says `I need a drink or something,be right back`

computers grade didn't distract me at all, but i think some of those grades were hilariously way off

I've taken it, but there is the usual caveat that you cannot grade accurately by picture. You need to see it in person to do it correctly.

I think I would be a lousy grader!

To me it looked like some of the coins were reused.

You know, I kinda thought the same thing.........is hard to grade pics though.

I didn't even know there were computer grades until I got half way though. Most of the computer grades seemed to be way off. Maybe that is ACG's problem? NOT!

The color also made it very hard to gradet the MS items - if they were. All of them looked cleaned or bassy.

I think some coins were reused as part of the test, to see if your grading opinion changed when a grade was given.

Some of the grades given were way off, but again I think it was designed to see if you would raise or lower your grade if a grade was given.

I will be very interested in the results of this test.
