1918-P Half Sovereign, NGC MS61

Estimate: $5,000 – $6,000

The undisputed key date of the half sovereign series and an enigmatic rarity.

The Perth Mint stated that no 1918 half sovereigns were ever produced. However, in 1967, an article in the Australian Coin Review published the first discovered example, and since then more have surfaced, with up to 300 specimens known, and problem free Uncirculated examples even scarcer. Further research since the article indicates that coins were struck in 1919 and 1920 bearing the 1918 date. Most were exported, with most melted, leaving surviving examples scarce.

The present example, graded NGC MS61 with cert number 4975403-006, is fully lustrous and Uncirculated. Rare, and the key date in the Australian Half Sovereign series.

Obverse with somewhat muted lustre, while the reverse remains fully brilliant with near-full original red colour. Likely stored for an extended period in an old press-in album.

A sharply struck example with no visible wear, and exceedingly scarce in this level of preservation.

Just six other examples have been graded at this level, with only a single specimen certified higher.


Very scarce with so much original colour remaining.

2000 Millennium Incuse Flag 50c, PCGS MS65

Estimate: $4,000 – $5,000

The Millennium Incuse Flag has long been a popular variety amongst collectors, though examples are seldom encountered in grades above MS63.

The present example, graded PCGS MS65, is one of just two certified at this level and ranks amongst the finest known of this scarce variety.


Fully as struck, with complete original lustre and minimal contact marks, it represents an outstanding example and is ideally suited to the collector assembling a high-grade set of Australian decimal rarities.

Fantastic business! I have purchased many sovereigns and half sovereigns for good prices and can always rely on fast and safe shipping methods straight to my front door. Really good communication and service too via email!! Highly recommend.

Robbie was knowledgeable and fair in our transactions. He traveled from Sydney specifically to assess our coins. Whilst being relative novices and understanding our shortcomings. Robbie was fair, and we were very happy with the result and the experience.

I have participated in 4 Copeland Roberts Coin Auctions this year and have found them to be professional, prompt with delivery after payment and have a large quantity and variety of coins that go to auction. They are now my preferred seller to fill the gaps in my collection.

Great team and quality customer service. Robbie was amazing and helpful in consigning items for an upcoming auction. I wouldn't hesitate to use Copeland Roberts again for future consignments, with their industry expertise, numismatic knowledge, and friendly support. Thank you

As a first-time consignor, I had a great experience with Copeland Roberts. Robbie and the team were all extremely helpful and communicative, and made the entire consignment process a breeze. I would highly recommend dealing with Copeland Roberts auction house.

Team was very helpful for an auction I took part in recently. Great auction, great experience, and I was very grateful to the team there for assisting me in getting the most from their first auction.
