Would .66 be the same as 2/3” lol, like the producing company used?

It would, but .65 or .67 could also fall into 2/3" so it is more precise!

Hah! It still sucks to use tenths, but we’ve been over that! If you are going to digress why not go all One World and switch to mm??

The makers had sections the marbles rolled down. If the marble fell between the 1/2" track, it was a 1/2" or maybe reject, if it fell through the 5/8" track, it was a 5/8" marble even though it might have been a bit less. If it didn't, it would go to the 11/16 or 3/4" slot, whichever they had set up, and it would fall through it and be called that size. A .66 marble would have gone to the 11/16" or 3/4" track most likely. Some makers even used the ought system, like double ought (00), and so on. They weren't so precise as we are now with these calipers.

I use a Wescott T-800 template to sort my marbles by size. It is about as close as I can get to what the factory did. 
If the marble does not fit through the 5/8” hole then it must be a 11/16”, in my world anyhow. I sort by factory sizes and am happy with that. Over 1 inch takes a calipers and clumsy sausage fingers. I drop more big ones than I do smaller ones.
Sellers are more fussy with sizes than I am, along with many buyers.
Marble—On!!

The producing companies used box end wrenches for checking size. They were 1/2 inch and 9/16 inch or 5/8 and 11/16 inch, etc. The wrenches hung on the marble machine at the start of the rolls. Done by vintage producer's, Jabo and current machine made marble makers.  The company boxed sets used zeros has size indicators. I have never heard of any machine made  marble company using 2/3 as a marble measurement.  But could be possible ?

my brain works in decimals i guess~!

Too much of the New Math being taught!! Maybe there is a generation gap here too!
