Rare $1 coin could be worth thousands due to simple printing error

A rare $1 coin could be worth thousands of dollars thanks to a distinctive printing error.

The “Mob of Roos” $1 coin with an obvious crescent-shaped defect could be worth $2000, according to coin experts.

The defective coins were minted and added into circulation in 2005 — along with 5.8 million other, non-defective, coins produced by The Royal Australian Mint in Canberra.

The crescent-shaped printing error partially cuts off three kangaroos on one face and the word Australia on the other.

An error such as this is termed an “off-centre”.

This occurs when the planchet, the metal disc the coin is made from, is fed through the press incorrectly when the coin is struck.

This particular coin seems to have been struck about 10 per cent — or 2mm to 3mm — off-centre.

Although a few of these coins are in circulation, they are not common.

So if anyone does find a coin that has been struck off-centre, chances are its flaws mean the coin is worth much more than its face value.
