Australian Opal Series – Rough-Scaled Python 2015 1oz Silver Proof Coin

The Rough-Scaled Python 2015 1oz Silver Proof Coin is the seventh release in the Australian Opal Series by The Perth Mint.

The mintage of this legal tender silver proof coin is limited to 8,000 coins. It features the rough-scaled python or scientifically known as Morelia carinata on its reverse, a python species that is native or endemic to Australia. This means the rough-scaled python is unique to Australia or ecologically limited to a specific geographic location.

No subspecies were recognized at the time of writing and it is said that the adult rough-scaled python, which grows to a maximum length of 6.6 ft (2 m) during adulthood, breeds readily in captivity. Despite its length, it is considered a medium-sized species and has unlike any other python species, keeled scales. The rough-scaled python also has forward-directed eyes, which allows for binocular vision. It should therefore not come as a surprise that this non-aggressive, easy breeding egg-layer is available for private ownership.


If you’re interested, you’re going to need a cage of minimum size 47.2441L x 23.622W x 23.622H (inches), keep the temperature between 82.4 and 95ºF and will need to feed it a rat once a week.

Hobbyists refer to the rough-scaled pythons as “Roughies”. Roughies are available at relatively affordable prices and you don’t need a lot of experience to take care of it in captivity. In fact, rough-scaled pythons are among the easiest python species, not only to maintain, but also to breed. However, if this still sounds like too much effort or if someone in the household will get hysterical in its presence, you may just want to stick to buying a couple or more of the python coins.

Needless to say, if you can handle both the python and the coin, you want to have your python coins on display in the presence of a rough-scaled python or two. Just imagine the following you will be able to attract via social media outlets such as YouTube.

Australian Opal

The rough-scaled python on the reverse of the coin is detailed in pure Australian opal, the national gemstone of Australia.

Opal is a hydrated amorphous form of silica, which is unlike other crystalline forms of silica, not classed as a mineral, but a mineraloid. The reason for this is because of its amorphous character, which is a result of its water content that can range from 3-21% of its weight. In addition, it is said that an estimated 97% of the world’s opal is mined or produced in Australia. Production consists 60% of white opal, 30% of crystal opal (pure hydrated silica), 8% black and 2% boulder opal.

Interesting enough the largest and most valuable gem opal in the world was discovered at the “Eight Mile” opal field in the South Australian town of Coober Pedy, a major source of opal. The relevant gem opal was named “Olympic Australis” and weighs a massive 17,000 carats or 7.60595 pounds (3.45 kg).

The Obverse

The Rough-Scaled Python 2015 1oz Silver Proof Coin features Her Majesty Queen Elizabeth II on the obverse and a face value of “1 Dollar” or 1 Canadian Dollar.
