Thanks for the compliment. The truth of life is that nothing is of value, when value is no longer taught! Coin collecting changed with the silver hype in about 1980 thereabouts with the Hunt Brothers and the predators who assumed the throne.
IMO
I not sure if grading Co's were in business before 1980.
It does seem like the Coin Hobby had to make a whole new grading system , that also "imho" has inflated prices (they are good for detecting counterfeits ) , also there has always been 'Cherry Pickers' of FBL , & Full Steps, Die types.
When a coin say goes from MS 65 - MS 69 & there is a 3 or 4 figure difference in retail & Street price. It don't make much sense to me (maybe if I had Millions to blow IDK) , I mean most coins that grade MS 60 - MS 67-or 68 look about the same to my eyes , It's a matter of opinion even to the grading Co's. Is MS or Proof 70 really "Perfect"?
In coins I like I'm completely happy to have a nice F -AU coin that has toning like on 'grandmas Silverware' It's my opinion but I don;t like my Old coins to look brand new. I really don't care for Rainbow Toning & other nice Toning but that's me.
My point? Heck I really don't know other than it seems the Coin hobby had to create a new grading scale, to keep the hobby going , Especially since 'most' of the Mint , Proof & commiserative sets produced since 1964 or so are basically worth their face value unless you just like the coin or it's made of a PM.
I guess when the SHT? these coins & collectibles will be worth their metal valve (you know when it comes to eating or having clean water = Coins Smoins

& When we pass-on we aint taking nothing with us.
This was a bit off topic I know , It seems Kid's teen's have a avg, 7 min attention span & this 'Including Me ' "I WANT EVERYTHING NOW CULTURE SCARES ME , HENCE THE OPIOID & Drug Epidemic around the world.
Stamps , Coins , Collecting does not get most younger peoples 'instant gratification' Juices / DNA Flowing like Food, drugs , Video Games , Oh Gaming does. Technology has helped us & hurt us. & Yes my 10 Y/O has an old smart phone but in a year he' s gonna want & need instant online info. I don't have a Smart phone but I find myself needing one just so i'm not left in the 1980's.
IDK sorry for that rant & i'm sure it will not come across as I wanted it to.
P.S. 95% of High Grade Morgan Dollars are UGLY AS HECK!
