The link says it's only in Shanghai Can't wait to see the difference between a common bronze grade 30 vs. 35
Not a fan of grading in the first place, even though I get mostly graded that I eventually crack out. I end up with graded since most of the auction houses here in the US (i.e Stacks and Heritage) slab the coins before putting them up. I like the old system--NGC for Ancients and PCGS for US.
Interesting. I don't mind slabs for modern coins but I usually crack out my ancients. I don't think the 70-point Sheldon scale will work well for ancients at all. I wonder why they didn't come up with their own ancients grade system like NGC did.
