The five cent coin with it's curled up echidna may become an endangered species.

That's if Queensland's LNP members get their way.

In one of 81 endorsements to be voted on during the party's three-day conference, a motion asking the LNP to propose to the federal government that production of the nation's smallest denomination of currency be stopped and the tiny coins taken out of circulation was carried.

The seemingly innocuous motion sparked a short but impassioned debate, with Young LNP member Debra Smith telling the convention the coins were basically worthless in modern society.

"It makes no sense to continue with a coin that costs one cent extra to produce then it's actually worth," Ms Smith said.
