Exploring Australia’s Most Sought-After Decimal Coin Errors and Varieties
Australia has a rich history of coin collecting, and error/variety coins have become a hot topic among collectors. These fascinating misstrikes can fetch high prices, making them a must find for collectors and investors alike. In this post, we’ll explore five of the most notable Australian decimal coin errors or varieties being the $1 Mule, the 20-cent Wavy Baseline, the Alien 5-cent, the $2 Bullseye Error, and the 50-cent Incused Flag. It should be noted that these errors and varieties are all caused during the minting process and not after a coin has been minted.
The $1 Mule (2000)
One of Australia’s most famous error coins, the 2000 $1 Mule, resulted from an incorrect die pairing during minting. This coin was struck using the obverse (heads) die of a 10-cent coin instead of the correct $1 die. The mistake created a distinct double rim around the edge, making it highly desirable among collectors. With values reaching thousands of dollars depending on condition, this is a prize find for any coin enthusiast.
The 20-Cent Wavy Baseline (1966)
Among the rarest and most valuable Australian error coins is the 1966 Wavy Baseline 20-cent piece. Found on coins minted at the London Mint, this error affects the number ‘2’ in ‘20’, where the lower horizontal line has a distinct wave instead of being straight. This subtle yet significant difference makes it one of the most sought-after coins, with well-preserved examples
The Alien 5-Cent variety
The Alien 5-cent coin is a striking misstrike that results in a distorted or extra metal protrusion from the echidna’s head. This anomaly gives the coin an “alien-like” appearance, hence the name. This variety varies in severity, with some being more dramatic than others. They are a favourite among collectors due to their unusual and eye-catching appearance.
The $2 Bullseye Error
The $2 Bullseye Error occurs when the paint on a coloured $2 coin is applied to the obverse side of the coin instead of the reverse side creating a “bullseye” effect. It essentially bullseye’s the portrait of the Monarch. The rarity and aesthetic appeal of this error make it highly collectible.
The 50-Cent Incused Flag variety
The 50-cent Incused Flag variety is found on some 2001 Australian 50-cent coins. Instead of the usual raised flag design on the Australian Federation emblem, the flag appears incused (sunken). This rare mistake has made the coin a popular target for collectors.
Why Collect Error Coins?
Error coins are unique pieces of history that showcase the imperfections of minting processes. They can be lucrative investments, with values often appreciating over time. Whether you’re an avid collector or just starting, keeping an eye out for these rare mistakes could lead to a rewarding discovery!
