That's interesting. considering you were at the sale and are well informed it would help if you could expand further please. Infact there were two their often bidding against each other. The main one bought most of the expensive coins offered. Without wishing to name names, "bidder 61" a virtually unknown figure at the start of the sale, sat in the corner and pratically bought all of the top end coins, like the 1820 gold five pounds, the Anne five guineas, the 1699 five guineas etc etc. I would hate to guess just how much he spent in the end. Both "bidder 61" and a Japanese buyer literally chased up the prices on all of the so called star coins of the sale. As investors they seemed to have, like someone mentioned earlier, a criteria of high grade and rare material only. There bidding patterns reminded me of such as on storage wars where one would shout £5000 the the next £10,000. Ultimately these two buyer won't effect the collectors markets which most of us on here are involved in. They aren't interested in normal every day pieces.
