History of the Australian 20 Cent Coin: From 1966 to 1968

In 1966, Australia transitioned from the British imperial currency system to the decimal system, bringing forth new coins. The 20 Cent Coin was introduced in the same year, alongside other denominations like the 5 Cent, 10 Cent, 50 Cent, and $1 coins. However, it wasn’t until 1968 that the coin underwent its iconic design change.

The original design featured an image of a stylized representation of the Commonwealth Coat of Arms, but by 1968, Australia’s currency began to embrace more distinctive national symbols. The 1968 coin featured a frilled-neck lizard on the reverse, a design created by Stuart Devlin, a renowned British-born Australian artist and designer.

This change in design was part of a larger effort to create coins that better represented Australia’s unique flora and fauna. Devlin’s design captured the essence of Australian wildlife, which resonated with the national pride of the time.

The Design of the 1968 Australian 20 Cent Coin

The 1968 Australian 20 Cent Coin features a striking image of a frilled-neck lizard, a creature native to northern Australia. The design, created by Stuart Devlin, was intended to reflect the distinctive and unique nature of Australian wildlife.

On the obverse, the coin features the effigy of Queen Elizabeth II, which was also designed by Mary Gillick, marking a continuity of design across Australian coins. The reverse showcases the frilled-neck lizard, with the animal depicted in profile, its frills extended, symbolizing strength and resilience.

This design is particularly significant as it marks a shift toward coins that showcased native Australian fauna rather than more generic, heraldic symbols. The decision to feature the frilled-neck lizard was based on its cultural significance, as it was a creature that was iconic to the northern parts of Australia. It was a perfect representation of Australia's biodiversity.

Devlin’s design work also included the careful consideration of the coin's size and weight, ensuring it was both functional and aesthetically pleasing. The coin's diameter, 28.5mm, and its weight of 11.30 grams, made it distinct in terms of its size compared to other coins in circulation at the time.

Minting and Production of the 1968 20 Cent Coin

The minting of the 1968 Australian 20 Cent Coin began shortly after the change in design was approved. The Royal Australian Mint, which is responsible for producing the nation’s currency, used the highest standards of production during the late 1960s. The 1968 20 Cent Coin was minted in both standard and proof quality.

The mintage figures for the 1968 coin are crucial in determining its rarity. In 1968, over 71 million coins were produced, which makes the coin relatively common in circulation. However, the number of coins in uncirculated or proof condition is much lower, adding to its rarity among collectors.

Over time, the condition of the coin has become one of the most important factors in determining its value. Coins that have been kept in pristine condition, free from wear and tear, are much more valuable than those that have been circulated.

Value of the 1968 Australian 20 Cent Coin: Current Market Trends

The value of the 1968 Australian 20 Cent Coin depends largely on its condition and the demand among collectors. Coins in uncirculated condition or higher grades, such as proof coins, are significantly more valuable than coins that have been circulated.

The typical market value for a circulated 1968 20 Cent Coin is relatively low, as it is still common in coin collections. However, the value of the coin can increase dramatically depending on factors such as:

• Grade/Condition: Coins in higher grades like MS65 or MS66 can fetch a premium.

• Rarity: Coins in proof or limited editions are far rarer and more expensive.

• Historical Significance: The 1968 design change and the use of the frilled-neck lizard add to the coin’s importance and market demand.

At auction, some rare examples of this coin, especially in uncirculated or proof quality, have sold for several hundred dollars, with the highest-value examples fetching more depending on market demand and collector interest.

Why the 1968 Australian 20 Cent Coin is a Collector's Item

Collectors of Australian coins are particularly drawn to the 1968 Australian 20 Cent Coin due to its historical significance and unique design. The coin is an integral part of the decimal currency shift and marks a significant moment in the nation’s numismatic history.

Over the years, the coin has become a symbol of national pride and interest in Australian heritage. The depiction of the frilled-neck lizard on the reverse side of the coin is a direct reflection of Australia’s diverse wildlife, which only adds to its appeal among collectors who value coins that reflect a country’s identity.

The 1968 coin, being part of the early series of decimal currency coins, also represents the initial years of Australia’s transition from British colonial currency. This historical context makes the coin not only a piece of numismatic art but also a symbol of Australia’s post-colonial identity.

How to Identify and Authenticate a 1968 Australian 20 Cent Coin

Identifying and authenticating a 1968 Australian 20 Cent Coin is a critical part of coin collecting. Due to its popularity, there are many counterfeit versions of this coin circulating in the market. Authenticating a 1968 coin requires knowledge of the coin’s key features:

• Size and Weight: The standard 1968 coin should weigh 11.30 grams and have a diameter of 28.5mm.

• Design Details: The frilled-neck lizard design should be sharp, with distinct features, including the frills and the tail.

• Edge: The coin has a reeded edge, which is characteristic of Australian 20 Cent Coins.

If you are unsure about the authenticity of a coin, it is always advisable to have it professionally graded by a trusted numismatic expert or service.

Caring for and Storing Your 1968 Australian 20 Cent Coin

Proper care and storage are essential to maintaining the value of your 1968 Australian 20 Cent Coin. Coins that are exposed to harsh environments or handled improperly can experience damage that decreases their value.

• Storage Methods: The best way to store your coin is in a protective capsule or holder that keeps it safe from physical damage, dust, and moisture.
