Copeland Roberts 019


Copeland Roberts is proud to present Auction 19, our largest auction yet, featuring 1,224 lots of Australian and world coins, banknotes, precious metals and numismatic collectibles.


Headlining the sale is an extraordinary 1934 Proof Halfpenny graded PCGS PR64RD—the sole finest example certified by PCGS and a remarkable full-Red survivor from Australia’s first commercially produced proof set.


The auction also brings together high-grade Australian pre-decimal coins, rare errors and patterns, significant gold and sovereign issues, modern decimal and silver favourites, world rarities spanning the sixteenth to twentieth centuries, and a carefully selected offering of Australian banknotes. With exceptional breadth and 1,224 lots, Auction 19 offers opportunities for collectors across every major area of numismatics.




1934, Proof Halfpenny, PCGS PR64RD


Estimate: $12,000 – $15,000

The single finest example certified by PCGS, with none graded finer. Retaining full fiery red mint brilliance with mirrored fields and frosted design elements, it is the definitive example of this landmark Australian proof issue and the cover coin of Auction 19.



1967, Pattern Swan Dollar, PCGS MS68


Estimate: $3,000–4,000

An exceptionally high-grade example of this iconic Australian pattern, with only two finer examples certified by PCGS. Brilliant, sharply struck and virtually free from contact marks.

2017, Sun $5, PCGS MS70. Top Pop.


Estimate: $2,000 – $3,000

Released in 2017 as part of the ever-popular Planetary Coin Set. Tied top pop with 11 other coins. Very rare and hard to achieve in MS70 grade.



1566, Hungary, Transylvania, Ducat, PCGS AU53. Top Pop.


Estimate: $4,000 – $5,000

An exceedingly rare gold ducat of John Sigismund struck at the Sibiu Mint, featuring the scarcer Madonna-and-Child die variety. It is the only example of the type certified by PCGS.
