Hi all -- I've been thinking about the prospect of automated coin grading. Slabbed coins from PCGS and NGC seem overly expensive, and people here have been reporting problems with them (e.g. the recent red spots thread).
Would you personally prefer an automated solution, if it was cheaper? By automated, I mean computerized, using machine vision and perhaps various multispectral scans of the coin beyond human vision. I know a bit about machine vision, and an automated solution to coin grading seems inevitable. I think it would be a somewhat easy task for machine vision experts, relative to the kinds of problems they solve currently, like understanding what's in an arbitrary photograph (faces, people, sky, balls, grass, cars, etc.). Coin grading would be a smaller, more delimited problem for them – the software would always know what coin it was grading and what it's supposed to look like at various levels of quality. It wouldn't have to worry about arbitrary objects in an image.
I'd be all for it if it cost a couple of dollars. It would also be nice if a service offered a more careful slabbing process, using a nitrogen atmosphere or vacuum sealing.
I bought this on a whim as you do,and after a lot of searching I can not find a Panda coin with this type of obverse design.Any help would be appreciated. I only payed £26 so can't moan really will be happy if it is silver.
