It's a good question - my plan here is to start narrow and then expand - the rarer the set the more scant the data for sure. It's something that we'd have to expand set by set starting with the cross section of popularity and value.
I will post a Dropbox link if anyone does want to post picture. I really appreciate all the above advice - I'll try to see if the images on VCP and the existing grading companies are large enough to warrant a web scrape...
