Others have bought them as "secret Santa" gifts.

And then there are the history buffs who just want to own a piece of Wagga's past.

The one thing in common among people who have bought bricks from a demolished old Wagga jail wall is their money is going to a great cause - Sunflower House.

The wall has come down to make way for a $17 million redevelopment of the Wagga court precinct.

Wagga court deputy registrar Jenny Mountford said 50 bricks out of the 300 on offer had been sold since last week.

The bricks, estimated to be more than 100 years old, cost $10 each and come with a numbered certificate of authenticity.

"We are doing quite well," Ms Mountford said of sales so far.

"It's generated lots of interest from people who want to how about the history of the court house.

"One person bought seven as a secret Santa gift.

"One fellow wants 20 for a barbecue.

"It would be terrific if we could sell all 300."

Ms Mountford said Sunflower House was "thrilled to bits" with the brick initiative because the donated money - hopefully $3000 - will be donated with no strings attached.

Sunflower House team leader Mary McKenzie described the brick sale as a wonderful initiative.

She said Sunflower House - which assists people with a mental illness - was extending its kitchen, and the money might go towards that project.

She said Sunflower House was also looking to raise money to help retain a part-time staff member who works three days a week.

Bricks can be bought from the court office at 49 Fitzmaurice Street.
