When the Mint Gets It Wrong: The Guide Every Australian Coin Collector Has Been Waiting For
Some of the most valuable coins in Australia are the ones the Mint never meant to make. A misstruck edge, a doubled die, a planchet flaw. These mistakes slipped into circulation and became prizes for sharp-eyed collectors. The challenge has always been knowing what you are looking at, and what it might be worth.
That is where the Renniks Australian Pre-Decimal and Decimal Coin Errors guide comes in. Edited by Ian McConnelly and published by Renniks, Australia's most trusted name in numismatic references, this first edition is dedicated entirely to Australian coin errors and varieties. It is a specialist resource we are pleased to offer at Mint Coin Shop for $34.95.
What makes this guide different
Most catalogues cover standard issues and leave errors as a footnote. This guide flips that around. It focuses on minting errors and die varieties across both pre-decimal coinage, the pennies, shillings and florins of the pre-1966 era, and the decimal coins we still use today.
That coverage matters. Error collecting is one of the fastest growing corners of Australian numismatics, and decimal errors in particular can still turn up in everyday change. Without a reliable reference, it is easy to overlook a genuine rarity or, just as costly, to pay a premium for a coin with ordinary post-mint damage.
Who should own it
This book earns its place on the shelf whether you are a seasoned variety hunter or a newcomer who just found an odd-looking 50 cent piece. It suits collectors wanting to identify errors with confidence, buyers and sellers who need to verify claims before money changes hands, and anyone curious about how coins are made and how the process can go wrong.
The details
The guide is a first edition, edited by Ian McConnelly, published by Renniks, ISBN 9780987338655. It covers Australian pre-decimal and decimal coin errors in a single dedicated volume.
At $34.95, it can pay for itself the first time it helps you spot a genuine error in a dealer's tray or your own coin jar. Order it online at Mint Coin Shop, operated by newsXpress, and enjoy free shipping on orders over $225.
Because sometimes, the Mint's mistake is your good fortune.
