How Much Longer Left For 5 Cent Coin?

I received a 2010 5c in my change last night. I don't usually check all that much but remembered reading here to keep an eye out for new issue 5c.

Maybe they will change to a different metal. Also in 1910 the half penny was worth 25 cents, so it makes you wonder why they keep the small coins at all.

Are you sure about that?

The Australian inflation rate during the Whitlam years sharp spiked at nearly 18%.
Average inflation rate without that spike is nearer 3.5% to 4%.

During the Great Depression, the inflation rate was around 2.5%

It is well worth knowing what the inflation rate history is.

I started collecting coins around 40 years ago, and I have marked what I have paid for the more valuable ones.

If they need to be sold, an inflation rate calculator such as this is a useful tool in helping to determine the selling price.

I have an inflation rate graph of the Australian inflation rate history that was released by Vanguard Investments to the investment advisor industry. It is possible to use this graph: I pick any two points along the graph and look at the absolute total inflation value between the two points.

To get the average rate per year, instead of the absolute different difference between any two years, I divide the top value by the bottom one, and use a reitrerative index function on my calculator to get the average rate.

This is worth knowing to find out the value of anything at inflated prices in the future, including my coin collection.

regarding inflation -
in 1907, Justice HIGGINS determined the "basic wage", sufficient for a man to support a non-working wife and three children, was 42 shillings per week (six days' work; one day's rest).
The pay for a Digger in WW1 was six shillings per day.
There were quite a few ups and downs in the 1920s and 1930s, but at the outbreak of WW2 in 1939, a Digger was still paid six shillings per day, although this was increased soon after.
Of course, taxes were a lot lower back then.
So, a half-penny was approximately 0.66% of a daily wage.
And if you extrapolate that to 25 cents today, that would imply that a daily wage of about $37.50 was sufficient ... hmmm.
So, it seems to me that it would not be difficult to make a case that a half-penny of 1910 is the equivalent of a lot more than 25 cents today.
Some other comparisons:
a visit to the Doctor in 1907 - 10s6d;
cost of a telegram from Melbourne to London - 10s6d per word;
which was a quarter of a working man's weekly wage.

We didn't make pennies but they were still around, you may argue about prices and wages but this goes on average inflation rate that includes costs goods. But you can not really compare the prices of two or more different time periods as a lot of things are different including technology and culture. Also it doesn't state the cost of minting a penny in 1910 or 11.
