312-year-old map has antiques valuation of C$600,000
The document has already been auctioned once this year.
A 312-year-old map of Canada is set to go under the hammer with an antiques valuation of up to C$600,000 (£378,779).
The hand-drawn item - which was uncovered last year in an attic of a Scottish estate - was created by 17th century cartographer John Thornton, PostMedia news reports.
It had an antiques valuation of around $120,000 when it went up for sale in the UK last month, but the price eventually reached around $320,000.
However, the 1699 piece is thought to be more than that, which explains why it is being put under the hammer once again.
Maureen Dolyniuk, manager of the Winnipeg-based Hudson's Bay Company Archives, said the organisation attempted to purchase the map, but it went for more than they could afford.
She added: "We have a record in the minute books of the Hudson's Bay Company that they purchased two copies of this map."
Another item randomly found in a house was a golden nugget, which was given a pre-sale estimate of up to £260,000 before going up for sale, the Metro reports.
