The 27,136 guineas average jumped 24% over last year and the 13,000 guineas median also showed a significant advance of 8%.
Two lots shared top billing with a price of 440,000 guineas. St Leger (Eng-I) fifth Tusculum realized that sum after Andrew Stringer, assistant to Newmarket trainer Barney Curley, outbid Andy Smith of the Havana Horse agency.
Stringer would not identify his client for the 3-year-old Sadler's Wells colt although Curley has acted in an advisory capacity to Germany's von Ullmann family, who previously owned Tusculum in partnership with Sue Magnier.
Europe's insatiable market for jumping prospects was in evidence when 3-year-old Purple Moon, by Galileo, made 440,000 guineas when selling to Irish agent Gerry Griffin. The colt will join trainer Nicky Richards as a potential hurdler.
The Al Qahtani family, buying for Saudi Arabia's Prince Faisal, were among other prolific top-level spenders, as was former trainer David Loder seeking Dubai Carnival contenders.
Among the U.S.-bound horses were 2-year-olds Golden Balls and Gilded, who were purchased by agent Gordian Troeller.
Redback filly Gilded, winner of Royal Ascot's Queen Mary Stakes (Eng-II), will join Vladimir Cerin after making 210,000 guineas, while Danehill Dancer colt Golden Balls, who realized 200,000 guineas, will race from Jim Cassidy's stable.
The 2-year-old Marju colt Bodes Galaxy – a 140,000 guineas purchase by Troeller – was bought for the same connections as Golden Balls after winning two and being G2/G3 placed. Juvenile filly Passified will race for Cassidy after making 125,000 guineas.
Agent John McCormack was also shopping for the U.S. market and paid 120,000 guineas for 2-year-old filly Fanlight Fanny, by Lear Fan, on behalf of a Boston-based client who has horses with Kiaran McLaughlin and Graham Motion.
"Withdrawals, or more specifically private sales, remain a frustration but that aside we enjoyed another hugely successful week and the vendors were richly rewarded for their confidence in the sale," remarked Tattersalls chairman Edmond Mahony at the close of play.
"Last year's Autumn Horses in Training Sale achieved records across the board and the 2006 renewal did the same except by far wider margins. Equally impressive has been the tally of six figure lots which rose from 24 in 2005 to 46 this year."
