How much did a sheep cost in 1350?
The record: 1s 5d, mid-14th c..
About $210 in today's gold
9 days of a farm labourer's pay.
A Somerset wether went for 9–10d. Source
Who could buy it
The lowest paid on each ladder of 1350 whose pay was enough:
On a day's pay
On a week's pay
On a month's pay
In other words, a real purchase: weeks of work for a farm labourer.
