Overall, it seemed to be a mixed result with the higher priced items 'generally' failing to meet low estimate at times, or not even being sold. The price listed by PBA Galleries at web site includes their 20% premium.
On a few items of fleeting interest to me (no bids submitted by me), a few of the older editions of club histories went for more than the high estimate. This was the case for Myopia (1975) and Seminole (1955) club histories. The 1978 Masters 'practice round' ticket autographed by Hogan and Demaret went for $720 versus presale estimate of $300/$500. Willing seller and more than one willing buyer helps !!!!!
So, in general, maybe the 'number' of 'bidding' big hitters were fewer.
As to PBA Galleries, I have always found them very helpful and very quick to fix any errors.
