This is more as an FYI post. I know many here use CoinsandCanada (which I think is a pretty good basic reference site)for pricing and stat info. I've noticed most auction values have recently fallen below averages shown on that site (including many key year coins). I realize getting the raw sales data from
ebay is probably more accurate but to better understand how the CAC stats are arrived at I emailed the CAC contact on the site. Couple of things stood out.
1. The stats go back approx 2.5 Years.
2. About 50% of Certified
ebay sales are captured.
