I went last nite for the 6:30 Third Session which
had GB, Commonwealth and WW and have to say I was surprised
at the high prices realized for many items.
Quite a few went over the estimate or even catalogue.
One item that blew me away was lot 1594 Burma 1-18
blocks of 4. Scott catalog $7680+ went for $10,000.
This has been only my second time and I didn't bid
on anything.
Maybe next time when I get the hang of it.

And as was mentioned previously , this Mr. Vance was the main bidder
and I would say he won at least half of the lots during
the time I was there.
