The two coppery ones look like drill PMD to me seeing as there is a circular pattern on them. The others look ok. |

i dunno, they nearly all look PMD to me. I wouldn't buy them because they look 'funny' <--- I'm no expert, just a regular buyer on ebayer and the 'funnyness' would put me off, genuine or not. |

I am no coin collector but I can 100% tell you they are genuine anyway there seems very little interest

How does anyone really know that these are Australian coin blanks? Is there any other foreign coin denomination that (within normal tolerances) that could also be the same dimensions and alloy.
Think of the old penny blanks. They could be Australian/British/NZ/South Africa/?/etc and if say blanks are scarce or popular in one country (to collectors) but common or unwanted in another then the enterprising/dishonest can make a killing.
The really dishonest could even make their own blanks. Its a lot easier to make a blank only than to make a blank plus a pair of dies to counterfeit money. Could you even be prosecuted with counterfeiting if you only make the blanks but not the dies? (Probably our enterprising "friends" in China could churn out blanks for hundreds of denominations, why pay $30 at a dealer for a tarnished penny blank when they can supply all you want for just a few dollars).

The reason these look PMD or otherwise in-genuine is that on 3 of them they already have a "Rim" on them. Blank planchets are totally flat and round before they are put in the press which creates the design and the rim with reeding at the same time. In my honest and limited opinion these only have any use is as a replacement welch plug in an engine  |

he he yes our china friends, I can get pre-decimal blanks made today delivered in 2 weeks by snail mail for $2 a pop. But why would anyone want a replica? Also there was a person in Europe that was selling error blank coins from the mint, probably an ex worker, anyway I picked up a cheap waffle error test type, end of run coin, because it looked so similar to an Aussie $1 blank. Mine blank is kinda similar to this link except is has more ripples and they go from end to end. http://www.ebay.com/itm/Blank-Planc...em484299759cEdited by Australian coin

I was thinking the same thing about the rim on the end.

Blanks are of no interest to me, as I consider them to be metal disks, nothing more, but each person has their own niche and if they appeal to you, all well and good.  They're not costing you anything to keep.  life is a mystery to be lived not a problem to be solved

Ha love it "a friend of a friend"
By law the mint is not allowed to sell minting machines! Most of the time they are sent to places like museums or they are destroyed.
Because people would make counterfeit coins.

I'm pretty sure that the strict security measures in place at the mint would require that any part of the press would be thoroughly cleaned and all coins/blanks would be removed then the parts would be destroyed by cutting up etc rendering the machinery useless before it left the mint premises. The odds of there being that many blanks left with the scrap when it left the mint are pretty steep. Regardless of what happened to the alleged press those "blanks" that your friend that got them of his friend and gave them to you that you have posted a pic of are not what you think they are. Look at my previous post and read why I consider that these are not genuine blanks. Edited by trout1105

Trout just for accuracy not all blanks are just flat discs. I just copied this from the RAM site Blanks for most circulating coins have their edge rimmed. This is a process where the edge of the blank has been raised by rolling the blank through a specially shaped groove. The raised metal assists in the coining operation by partially forming the rim so that the dies do not have to displace as much metal. |

I stand corrected.   Thanks for that AA  |

You either have a blank or a rimmed blank.
