Uncirculated and extremely rare at this quality level
Monetarium Adelaide 2007, Private Collection Queensland
This 1923 Halfpenny is fabulous. Fabulous, because the coin has great eye appeal, highly reflective fields, crisp design details and superb edges. But, it's under the eye glass that this coin truly shines. The collector that owns this 1923 Halfpenny, also owned the Holey Dollar and Adelaide Pound we sold late last year. Sold in a flash we add. He pursued Australia's classic coin rarities, the 1930 Penny, 1923 Halfpenny, Holey Dollar and Adelaide Pound, his priorities always that the coins had to be visually appealing. And they had to be technically correct. He waited a long time to acquire this coin and our research confirms the reason why. High quality 1923 Halfpennies are excruciatingly rare. This is the second only Uncirculated 1923 Halfpenny we have sold in our entire career. (Technical shots are provided in the READ MORE section and attest to its supreme state.)

The 1923 Halfpenny is a classic Australian rarity with an elite status.

The coin is Australia's rarest halfpenny and enjoys a constant stream of demand. 

Furthermore, the coin is scarce. Only 15,000 are believed to have been struck.

It's also extremely rare in high quality because the halfpenny, as a low denomination coin, was well used.

Our research confirms that a collector that is looking for a high grade 1923 Halfpenny (quality level of Good Extremely Fine or better) will check out at least one hundred coins before he finds one worth considering. And how long will it take for the one hundred coins to come around? Not quickly, that's for sure. 

This 1923 Halfpenny is a stand-out piece. Brilliantly struck and obviously cherished in the ninety-nine years since its striking. Its state of preservation is remarkable.


A stunning reverse, highly reflective surfaces with original lustre. Solid inner beading and date '1923'.


An amazing obverse. The diamond is sharp, complete and three-dimensional. The eight pearls are pristine. Smooth, highly reflective fields.

Australian collectors just love their copper coins.

While not everyone could hold onto (or even gain access to) a gold coin, the nation’s coppers were accessible to the man in the street.

And while there is no doubt that Australia’s 1923 Halfpenny has benefited from the emotional feelings stirred up by its side-kick, the 1930 Penny, the ’23 stands on its own merits as Australia’s rarest halfpenny.

And an Aussie icon.

This coin is one of the finest examples of the nation’s scarcest halfpenny.

It is in a remarkable state of preservation with highly reflective, smooth surfaces.

As a company we appreciate top quality. But more than top quality we love to see the words ‘exceptional quality’ ascribed to a piece. And this coin is exceptional for quality.

A rarity that defied the mintage figures.

That the Sydney Mint in its Annual Report recorded the striking of 1,113,600 halfpennies in 1923 would tend to suggest that it was a common date coin.

For decades collectors challenged the point, drawing on their experience that the 1923 Halfpenny was the least available coin in the halfpenny series.

John Sharples, at the time Curator of Australia’s National Coin Archives set the record straight when he undertook an analysis of die production and die usage at both the Sydney and Melbourne Mints.

His research confirmed that the 1,113,600 halfpennies struck at the Sydney Mint were in fact dated 1922.

The 1923 Halfpenny was in fact struck at the Melbourne Mint in a mintage of approximately 15,000, confirming its status as Australia’s rarest circulating halfpenny.
