Hastings Pier is being rebuilt with £14m of money raised mainly through the Heritage Lottery Fund.
It is now hoped a further £300,000 can be raised by selling 3,000 shares for £100 each.
The charity behind the restoration said investors would have a say in the pier's future.
The 140-year-old structure was almost completely destroyed by fire in October 2010.
Simon Opie, CEO of the Hastings Pier Charity, said the shares were important to continue interest in the pier after its restoration.
He said: "[The shares] are not just about the money, but it is about creating shareholder members, people who are invested in the pier, people who care about the town, the heritage of the pier, and people who will be here for the long term.
"The money that we have raised will restore the pier but beyond that it needs to have an economically viable future and that's what we hope we will create."
The Panamanian company Ravenclaw, which owned the pier, was issued with a compulsory purchase order after it failed to carry out repair work.
The order was granted in 2012 and the council formally took ownership of the pier in August.
It is hoped the restoration will be completed by spring 2015.
Hastings Council leader, Jeremy Birch, said: "This is the people's pier so let them have a stake in it."
The shares will go on sale on Saturday through a community shares website.

Livi's 2-0 win over their nearest challengers came courtesy of goals from Dale Carrick and Nicky Cadden.
Brechin City moved above Alloa Athletic and to within a point of second place by beating Stranraer, with the Wasps drawing with Queen's Park.
East Fife won Barry Smith's first match in charge against Peterhead and bottom side Stenhousemuir beat Albion Rovers.
Carrick's shot gave Livi an early lead at home to the Diamonds and Cadden's late strike sealed the win for David Hopkin's side.
At Glebe Park, Ally Love fired Brechin ahead on the quarter-hour and that lead was doubled by Connor McLennan's free-kick before half-time.
Stranraer had Steven Bell sent off in the second half for two bookings.
Queen's Park went ahead away to Alloa through Ross Millen's 62nd-minute shot, but the hosts were level within seven minutes through Greig Spence's strike.
The Fifers moved out of the bottom two after scoring two second-half goals against Peterhead, Jason Kerr then Kevin O'Hara firing in.
Smith's side were replaced in ninth by Stranraer, who are only two points ahead of Stenny.
Willis Furtado's strike gave the Ochilview side a narrow home win.

Musgrove Park Hospital said the cause of the "technical issues" in the hired facility was being investigated.
Surgery was carried out on 62 patients with just under half reporting complications while some 15 people had "more significant" corneal issues.
The use of the mobile facility was ceased when the issues were discovered.
All affected patients have been spoken to and care plans are now in place for their ongoing treatment, a hospital spokesperson said.
Vanguard Healthcare had been hired to provide the theatre to help clear a backlog for some ophthalmic services.
The unit, which consists of an anaesthetic room, operating theatre and two-bed recovery, is at the hospital until the end of the year.
Vanguard said it was "co-operating fully" with the hospital for the investigation which would focus on the drugs, equipment, sterilisation and protocols used.
"The majority of operations were successful, however a number experienced an unusual level of discomfort after surgery," added a spokesperson.
"We have, with the hospital, conveyed to the patients our concern and sympathy for the discomfort or distress they have experienced."
The hospital's chief executive, Jo Cubbon, said the issues meant many patients who had already waited longer than they should have, will now have to wait again for their operation.
"We are very sorry this has happened and are working to put a solution in place so that these patients will receive their treatment as soon as possible," Ms Cubbon said.
Shares in a derelict seaside pier that was almost destroyed by fire three years ago will be offered to the community to aid its restoration.
