One more thing to consider, and I admit it is just my own idea. TPG
's started out as a unique idea for someone to find a way to make money from the coin hobby. As always Americans went for it (note most the rest of the world believes they are able to do their own grading without having to be told by someone else like a TPG
I knew one day there would be someone brave enough to suggest the TPGs were not good enough and people would pay good the money to verify their already, "professionally" verified/graded coins had been labeled properly. So now we have the green bean.
I know the tech has existed for years to make a non-biased computer generated grading system that would remove human error and opinions (except the for the programmers making the algorithms for the computer to use!). In fact one of the large companies actually, (I think it was in the 90s), said they were going to switch to computer but did not.
Could it be their marketing dept. looked ahead a little and realized the amount of coins to be slabbed (old ones) had to one day start to dry up; hence they would have a lot less money coming in; and decided to put it off the computer grading for awhile so that when things started slowing down greatly, they coul dproffersomethinglike:
Dear coin community, you know we have done our best in the past to become a trusted company. You know out serviced have raised the quality and confidence level in the hobby. But we also know al humans are prone to error. We havegreat news in that we have found a way to eliminate that error forever! Our brand new computer grading system can accurately grade all coins using the same exact standard each time. Wouldn't you rest easier knowing your slabbed coins have been non-biasly graded to perfection? By re-submitting your old slabbed coins, you will be guaranteed a better appraisal. The more slabbed coins we can have computer-verified, the better the base of knowledge becomes for each date and MM! Send in your slabbed coins today - for the ridiculously low price of...
You get the idea. Personally, I would not be surprised to see the businesses find a way to cleverly tell us we need a new standard and the "old" slabs just aren't good enough. The old MS70's could/would lose value. I admit I've only been around ~50 years, but as time goes on, I am increasingly getting tuned into what really happens in our society. I predicted the concept of the green bean and it used to be a joke we all laughed about not believing anyone could ever "pull a fast one" like that b/c no collector would be willing to part with their hard earned money to have another "expert" verify what an "expert" was already paid to do. Oh well... we should not have been laughing!
And I may be wrong. And to anyone who collects MS70 slabs, I sincerely
hope you get the chance to look back and say, boy Earle42 was crazy!
