JoannI was just looking again through ebay and a few of the other online auctions. I noticed by how many of the high-end T206's looked small. And it struck me - how often do you see a really big border on some of these high grade cards.
No - just stop folks - this isn't about bashing or to start that whole hoo-ha again. It's an honest question about proving or disproving the issue.
Why couldn't someone measure several hundred, or more, T206's that are lower grade like VGish - measure both t/b and side to side. Then do the same to some high grade slabbed (or not) cards - just anything that would grade a 7 or better, for instance.
Then basic hypothesis testing on the means would give you a certainty that the two samples (VG and 7+) did or did not come from the same population. Because if the higher end cards are trimmed in greater number, the stats should tell you that the difference in size is statistically significant. Or not.
Aside from having access to that many cards, this seems to simple to me. Has it been done?
