Abbotsford Station manager Antony "Sparky" Nichol, the son of farm owner Jenny Nichol, put up more than 800 ewes and nearly 5500 lambs for sale on the more than 1700ha sheep and beef farm at Lee Stream, on State Highway 87, north of Outram.
The sheep on offer last week were a mix of Texel and Romney.
Ewes sold for an average of $153, fetching a top price of $170.
Mr Nichol said four generations of the family had owned the farm for more than a century.
Annual on-farm sales had been held for about 15 years.
The record price for a lamb was $115, he said.
For the first time, Romneys had fetched higher prices than the Texels.
His daughter, Sophie, told Southern Rural Life she was sad that her pet ewe, Marshmallow, was for sale but was buoyed by the news it had sold for $170, which her grandmother, Jenny Nichol, would let her keep.
At the sale, Mrs Nichol recalled that when her son was a boy and he told his parents he was ready to put a pet sheep up for sale.
When asked to confirm the story, Mr Nichol laughed.
"It must be in the blood," he said.
