The Western Australian Aboriginal shield, painted and carved spear and boomerang will be the highlight of the next sale at auctioneers Golding Young & Mawer on Wednesday, December 19.
Auctioneer John Leatt said: "This is the second significant collection of Aboriginal art we have seen in the saleroom this year.
"There is a strong collectors market for such items internationally and we expect a great deal of interest on sale day. We anticipate the collection will make a hammer price in excess of £1,000."
The vendor, who does not want to be named, inherited the items from his sister who lived in Lincoln and sadly died earlier this year.
He said: "The spear is a corroboree spear which was used in special Aboriginal tribal ceremonies and is very rare.
"My mother and father were given the spear, shield and boomerang as a gift from a missionary lady who worked in the far north of Australia near the Torres Strait in the Gulf of Carpentaria in around 1958.
"My father was a vicar working in Australia at the time and this lady was very fond of my parents. She also offered them a fish spear but my mother declined it. However they were delighted and overwhelmed to receive the gifts and they took pride of place in their home for many years.
"When my parents passed away, my sister asked for the collection and displayed then on a wall in her home. We both had happy memories of our time in Australia."
In August this year, a rare Aboriginal broad shield, submitted as part of the BBC's Flog It! Programme, made a hammer price of £30,000 at Golding Young & Mawer. The final bid was made by the Sydney Museum of Primitive Art on the telephone with the under bidder being a leading Australian gallery dealing in such artefacts which was bidding on the Internet
The figure was a new record for tribal art at Golding Young & Mawer, beating a group of lime spatulas from Papua New Guinea which sold in December 2009 for £26,500.
A corroboree is a ceremonial meeting of Aborigines during which they interact with the Dreamtime through dance, music and costume and tell the mythical history of the tribe.
Elsewhere in the sale, a late Victorian double gas powered magic lantern is expected to sell for between £800 and £1,200 and there is also selection of slides to fit. A very good quality binocular microscope made by Ross of London, which is being sold with various lenses and attachments, has an estimate of between £400 and £600.
A strong furniture section is launched by a good quality, early Victorian mahogany extended dining table with three extra leaves which is estimated to sell for between £2,000 and £3,000.
The bygones section features a number of enamel signs, the highlight of which is a brightly coloured sign by Sunlight Soap which was consigned from a house clearance to the North East of Lincoln. The sign offers a 'reward of £1,000 to any person that can prove that this soap manufactured by Lever Brothers contains any form of adulteration whatsoever'.
Mr Leatt said: "This is a rare sign in wonderful untouched condition which, considering it was probably on display in the late 19th century, shows great confidence in their brand.
"There is a strong collectors market for such signs, particularly very decorative signs such as this, and we expect it to sell for between £200 and £300."
Among a series of 30 lots of postcards in the bygones section, there is a collection of postcards relating to Lincolnshire and the surrounding areas which came from a property in the centre of Louth.
Elsewhere in the sale, there are between 100 and 200 lots of silver and jewellery including wine coasters and cutlery perfect for the Christmas dinner table. Other items that would make ideal Christmas presents include small boxes and snuff boxes, collections of Beswick, Beatrix Potter, Crown Derby, Disney Showcase figures of Snow White and the Seven Dwarves, Micky Mouse and Winnie the Pooh and Portmeirion Holly and Ivy dinner and tea ware.
There are also collections of cameras and toys including lead soldiers and animals
