commemorative coin photos
Im not sure the photos of the post-1969 commemorative coins can be used because "The Commonwealth holds copyright in the designs and images used on Australian currency coins which were created after 1 May 1969." (This was the reason I used 1966 coins in the article) -- Astrokey44 |talk 02:04, 26 January 2006 (UTC)
 * They are a photo (2d representation) of a 3d object which I believe does pass the copyright test--A Y  Arktos 02:19, 26 January 2006 (UTC)
 * In that case, the $1 and $2 could go in the article -- Astrokey44 |talk 12:08, 26 January 2006 (UTC)
 * in relation to these 2 images, the uploader has used the word "scan", I suspect they are not a photo and are copyright violations. Do you agree?--A  Y  Arktos 20:32, 26 January 2006 (UTC)
 * The word "scan" seems to me like a scanner, which would be a photo representation. I don't understand why that would change the status of copyright.   Joe I  21:08, 26 January 2006 (UTC)
 * The picture was not taken by the uploader, is quite possibly a scanned image from a publication ie 2d -> 2d which would be breach of copyright. Photos of coins are 3d -> 2d, not in breach of copyright.  It would appear that English was not the uploaders 1st language though and/or it is possible that the images of the coins were from original coins placed onto a scanner.  --A  Y  Arktos 03:14, 27 January 2006 (UTC)
 * Hi guys, not really a numismatics fanboy but I do happen to have a scanner and a pocketful of change! I have gone and made little black-background images showing the front and back of each Australian coin in circulation (eg) as well as a comparison image . Also, if anyone has any interest in the commemorative 50c pieces, I have scanned a selection but have no desire to go and cut them all out onto a black background, also they have pretty bad bagmarks. Just leave me a message on my talk page if you would like the original image to have a crack. Bilious 03:19, 12 February 2006 (UTC)
 * If youre going to scan post-1969 coins could you upload them to Wikipedia, rather then commons because they are copyrighted images. Commons does not allow fair use images, but Wikipedia does: they can be loaded to Wikipedia with the template -- Astrokey44 |talk 02:28, 14 March 2006 (UTC)

why the hell...
doesnt this article mention why the $1 is bigger than the $2? does anyone know? Plough | talk to me 00:25, 22 February 2006 (UTC)
 * Not sure why not but Australian coin sizes are not proportional to their value - the 50 cents is the biggest coin.--A Y  Arktos 01:00, 22 February 2006 (UTC)
 * My size comparison image does a reasonable job of showing size comparisons. I don't think many currencies in the world have coins sized in proportion to their value. Bilious 01:11, 28 February 2006 (UTC)
 * Simply, that the $2 coin was designed and minted some time after the $1 coin. The dollar coin was already on the large side, and an even larger and heavier coin would have been unwelcome. (For automated coin sortage, it would have had to be considerably heaver than the existing 20c coin: Ouch!) So the smaller design was chosen. This does leave us stuck for room when it comes time to make $5 a coin.Robbak 02:53, 9 September 2006 (UTC)

It used to be that way when coins were minted from silver, but no longer. For example the Canadian/US dimes (10c) are smaller than the nickels (5c) or pennies (1c). When nickels were minted from silver many years ago they were much smaller than the dime, and of course the penny was always copper. --207.161.47.68 15:31, 3 March 2006 (UTC)

$2 coins are smaller than $1 coins but $5 coins are the biggest.


 * But the $5 is a commemorative issue and not for gereral circulation, I belive it is becaus of the price of the metal and not wanting to make bigger coins in the future. Enlil Ninlil 05:10, 9 September 2006 (UTC)

Why is there a woman whipping a bird?
On the 50 cent student design for the 2006 commonwealth games why is there a woman whipping a bird? What sport does this represent!?


 * She isnt whipping the bird but mimicing it, but Gymnastics la Enlil Ninlil 02:28, 23 March 2006 (UTC)

Article name
I notice at WikiProject Numismatics/Style it says the standard format for article names is Coins of Australia not Australian coins. I propose a page move of this article to align to the standard. -- Chuq 08:45, 22 May 2006 (UTC)


 * Well, I'm usually always right :) There have been lots of renames, and moves and such for article names, and frankly, I'm tired of it.  Naming policy is true, as far as I know, tho, so have fun on all articles...:)   Joe I  12:29, 22 May 2006 (UTC)

Australian 50c 1966 Silver
Have just tried to adjust the figures in your article, there are 94.12 coins to make up One Kilo of Fine Silver. And the multiplication figure for XAU would be 0.3416 (they were the figures when I went to school)


 * You're right. My apology.
 * Round A$0.5 = 13.28 g * 800‰ = 10.624 g
 * 1000 / 10.624 ≈ 94.12650602
 * 1 troy ounce ≈ 31.103477 g
 * 10.624 / 31.103477 ≈ 0.341569529
 * --Chochopk 16:25, 25 July 2006 (UTC)

And a further follow-up, it's XAG not XAU (was following the lead article) Hope that helps, Brenton.

Pieces of Eight
Spanish dollars were sometimes cut into "pieces of eight"

While the coins may have been cut up I don't think this is why they're called "pieces of eight". See the article on the Dollar. It says that a Dollar was worth eight reals and that this is the real reason for the name. Ironcorona 00:00, 23 August 2006 (UTC)


 * You are correct, they were cut up to use as change but usually only in half or quaters. If you want to change it you can but please reference it. Enlil Ninlil 05:55, 23 August 2006 (UTC)

Possible error on this page.
The comment: "Guinea = £1/1/- (One pound and two shillings)" appears to be incorrect. I would expect the brackeded comment to read Guinea = £1/1/- (One pound and one shilling) This statement is from a logical viewpoint as I am uncertain of the Guinea coinage value. (Gholdsworth (talk) 23:47, 31 December 2007 (UTC))

Bronze mixture usage?
Does anyone know what mixture the Australian mint used to make Bronze coins? I have come across conflicting information. For example:

•were the old Halfpennys 970 parts Copper, 25 parts Zinc, and 5 parts tin? Or 975 Copper, 20 Zinc, and 5 tin?

•were the old one cents 970 parts Copper 25 parts Zinc, and 5 parts Tin? Or 970 Copper, 25 Zinc, and 5 Nickel?

•etc.

Thank you.
