Were you able to view the lot in person? I know even the big auction houses have trouble catching a coins true appearance at times. At the last ANA/Heritage auction that I was able to attend in person the on-site lot viewing I did completely changed how I was bidding.
That said, there are definitely crazy prices in the areas that I collect and it is not often that I can view lots in person prior to bidding. I don't have deep pockets so I have to be picky what I bid on. Going into a big auction I may have 6 items that I am both interested in and feel like I have a chance of obtaining. Out of those, I may only bid seriously on 1 or 2 of them. Attached is my most recent auction win. I ended up paying 4 times the estimate but the estimate was rediculously low. This came from the CNG sale earlier in the week. They actually had videos posted of most of the items in the sale which is important to me. If interested it can be seen here. https://cngcoins.com/photos/CNG_Links/video/CNG_118/1277.html
Still not as good as an on site inspection but in my opinion, more informative than a photo.
