For most of us, pocket change is just that—spare coins tossed into drawers, cars, or jars. But what if some of those forgotten pieces are actually hiding unexpected value? In Australia, certain coins are now worth hundreds—or even thousands—of dollars to collectors.

If you're holding onto older change, it might be time to take a closer look.

The 2000 "Mule" Dollar Coin

This coin looks like any ordinary $1 coin at first glance—but it’s anything but. Due to a minting error, it features a double rim on the Queen’s head side. Only a small number made it into circulation, and today, these “mule” coins can fetch over $3,000 AUD depending on condition.

1985 and 1995 10-Cent Coins

Think 10 cents can’t go far? Think again. The 1985 and 1995 editions are extremely rare in mint condition. While they may appear normal, these specific years saw very low mint numbers. In uncirculated condition, they’ve been known to sell for $100 AUD or more.

1966 Round 50-Cent Piece

When Australia moved to decimal currency in 1966, the original 50-cent coin was round and made of 80% silver. Its metal content alone makes it valuable—often worth 10 to 20 times its face value. But pristine or uncirculated versions can go for even more among collectors.

Commemorative and Misprinted Coins

Coins that feature unique designs, limited-run issues, or striking errors are often the ones collectors seek out most. Examples include:

2010 "Upset Die" $2 coin – where the Queen's head is rotated slightly off-center.

ANZAC and Remembrance Day coins – certain color ringed $2 coins from 2012–2016 are fetching high interest.

How to Check Your Coins

It doesn’t take special equipment to spot a valuable coin. Just flip through your spare change and check the:

  • Year — Low-mintage years are key.

  • Design — Look for unusual patterns, misalignments, or double strikes.

  • Edge — Inconsistent or missing edge inscriptions can indicate a rare error.

And if you’re unsure? Many local coin shops or online communities offer free evaluations.

What you’ve got in your change jar might surprise you. These coins aren’t just currency—they’re pieces of history. And for some Australians, they’re becoming an unexpected payday.
