Coin Grading Machines are here!

solid

"In May of 1990, after more than two years of development, PCGS demonstrated
a coin grading machine called "PCGS Expert" and stated they had begun using it
to grade coins."

"Computer machine grading has thus arrived and promises to give consistent
grading."

"Ultimately the improved grading capabilities offered by computerized grading
machines will lead to more consistent grading and to the betterment of the hobby."

Quotes from the 4th edition of the Comprehensive Catalog and Encyclopedia of
Morgan & Peace Dollars, by Leroy C Van Allen & A Geaorge Mallis (copyright 1991).

I guess nobody noticed...

We noticed. There have been multiple threads on "The Expert" and how it was a failure.

How it worked and why it failed

I know it's been discussed here - I was just doing some reading and ran
across this section of the book and found it interesting that, 13 years
later, we are probably no closer to this reality.

Personally, I think it will be a long time before a capable machine is
developed as there are just too many variables. I do believe it is
inevitable that collectors will come to trust such a machine; it's just
a matter of whether it's 10, 25, 50 or 100 years down the road.

I thought this was going to be a thread about MadMarty.

Actually, the machine came to life and they named it Jim Halperin

The Halperin coin grading article that includes a chapter about that machine is on this webpage.

It will never happen. Too many intricancies. Too many ways to doctor a coin that a machine can not identify. Also, it currently takes what, 3 - 10 seconds for a grade to be determined by a human, how long would it take a machine? Shoot, it would take longer than that just to load the coin into the machine. Just think of the turn-around times then!!!

Wasn't there a service called DCGS recently that tried to grade coins using computers and failed?

The thing is, you could pay some guy minimum wage to run coins through the machine. He wouldn't have to be an expert on coins, wouldn't have to be paid a huge salary, etc. So even if it took longer to grade by computer, you could have multiple computers and multiple workers and run through the same number of coins per day.

Computer grading will never work and that should be comforting to all of us. The industry thrives on subjectivity, even certified grading by highly regarded experts hasn't changed that. The human element drives the hobby and the best dealers are numis-psychologists who understand that.

I never knew about any of this so I'm glad it was brought up.

hows it goin jerry.

computer grade could work, but only when all can agree on a set standard.
coin grading in and of itself it so subjective.
maybe they can develope a machine with an occasional bad attitude?
