Best "guide" for grading coins

Right, so it's not the images that are directly expensive; it's the paper quality and page count necessary to make the images useful.

Dare I say that some of the very same AI infrastructure that will be making computer grading possible is ALSO the very same tech that is helping in improving counterfeits? Tech giveth, and tech taketh away.

 

As in just about every S/B or Heritage big auction catalog? I have never found them lacking, at least recently.

 

I don't think you understood my comment, or perhaps I wasn't clear.

You said "hi-res images are ridiculously expensive to print."

And, "It'd take a full page per single image."

All I was saying was that image resolution, in itself, isn't a cost factor, and doesn't dictate that the image must be printed at a prohibitively large size, dimension-wise.

 

I'll defer to your obviously greater knowledge of the process, but my worry was more about the extra pages involved than the cost of the resolution, with the implied idea that 300dpi has no use for a 3" image.

I post images here at 75dpi usually, and nobody complains about them.

 

Yup, best resource there is for higher end material.

 

I had to get a stronger bookshelf for mine. Dang things are so heavy I thought it was going to break.

So far (first two chapters), your grading book is terrific in spite of the pictures (I skipped ahead to take a look).

 

30 linear feet of bookshelf space for me - auction catalogs alone.

 

I have heard that one of the researchers at NGC has OVER 70 feet of books if you count the one's he keeps at home and the office.

 

Yeah, I might too if my work involved coins, but it doesn't. It involves laws.
