'''Mint Marks:'''
=== Mint Marks ===
The 1966 10c coin was minted at both the Royal Australian Mint in Canberra and the London branch of the Royal Mint. Distinguishing between the two coins is relatively straightforward.


The two different variants of the 1966 Australian five-cent coin minted in London and Canberra can be readily distinguished by a key visual difference in their reverse designs. Specifically, the length of the spine on the echidna's front right shoulder is notably longer on the coins produced at the Royal Mint in London compared to the shorter spine on the Canberra-minted coins from the Royal Australian Mint.
To identify the mint origin, examine the reverse side of the coin, focusing on the three lyrebird feathers towards the top. The key difference is found on the center feather: on the Canberra coin, the last spur of this feather has been removed.


This subtle but distinct design variation provides a helpful diagnostic feature for collectors and enthusiasts seeking to differentiate between the two 1966 five-cent coin varieties. The longer spine on the London-minted coins creates a more pronounced and pronounced quill-like appearance, whereas the Canberra coins have a shorter, less emphasized spine on the same part of the echidna's body.
In contrast, the London-minted coin retains the spur. The images below illustrates this difference, with the spur circled on the London-minted coin and the same spot (with the missing spur) circled on the Canberra-minted coin.


In terms of production numbers, the Royal Mint in London struck 30 million of the 1966 five-cent coins. Meanwhile, the Canberra facility of the Royal Australian Mint produced over 45 million examples of the 1966 five-cent piece. As a result, the Canberra-minted coins are the more prevalent and commonly encountered of the two 1966 five-cent varieties among collectors and in circulation.
There are no observable mint marks on London and Canberra 1981 coins.


This clear visual distinction and difference in mintage figures makes the longer vs. shorter spine on the echidna's front right shoulder an essential diagnostic tool for identifying the origin mint of individual 1966 Australian five-cent coins. It's a key detail that numismatists and coin enthusiasts can use to accurately attribute and catalogue examples of this important decimal currency issue.

Production

The ten-cent coin was first introduced as part of Australia's transition to decimal currency on February 14, 1966. This transition marked a significant change in the nation's monetary system, moving away from the pounds, shillings, and pence system to a more straightforward decimal system.

The original reverse design of the ten-cent coin features a lyrebird, an iconic Australian bird known for its extraordinary ability to mimic natural and artificial sounds. Remarkably, this design has remained unchanged since its introduction, making it a consistent and recognizable symbol on the coin.

While the reverse design has stayed the same, the obverse design underwent a notable alteration in 2016. This change was made to commemorate the 50th anniversary of the introduction of decimal currency in Australia. However, the steadfast lyrebird on the reverse side continues to grace the ten-cent coin, preserving a piece of the original design for collectors and the general public alike.

The production of the ten-cent coin began with the first issues in 1966, all of which were minted at the Royal Mint in London. Following this initial production run, the responsibility for minting ten-cent coins shifted to the Royal Australian Mint in Canberra. This transition reflects the evolving nature of coin production and the collaborative efforts between different mints to ensure the availability of ten-cent coins for circulation in Australia.

Mint Marks

The 1966 10c coin was minted at both the Royal Australian Mint in Canberra and the London branch of the Royal Mint. Distinguishing between the two coins is relatively straightforward.

To identify the mint origin, examine the reverse side of the coin, focusing on the three lyrebird feathers towards the top. The key difference is found on the center feather: on the Canberra coin, the last spur of this feather has been removed.

In contrast, the London-minted coin retains the spur. The images below illustrates this difference, with the spur circled on the London-minted coin and the same spot (with the missing spur) circled on the Canberra-minted coin.

There are no observable mint marks on London and Canberra 1981 coins.

Variations

1999 Large head / Small head

The 1999 Issued coin had large and small QE II head varieties, the large head (letters near the rim) is rarer than the small head (far from rim).
