Unsure about clipped coins now days they are so easy to fake.
Clipped coins used to be with the old soft metals, like copper and silver.
With a bi metal coin like a $1 it's not likely to happen naturally. I did see some doubling with the kangaroos legs like a double stamp.
Most coins on
ebay that I see like penny's that have been so called clipped are a simple job with tinsnips or sheers and they are easy to spot. A true clipped coin should have a neat edge. Not squashed in the middle.
What? Pretty much everything you posted there is plain wrong.
Firstly, the old 'copper' and 'silver' coins were alloys exactly the same as Aluminium Bronze dollars.
Secondly, a coin made from an alloy is not a "bi-metal" coin. A bi-metal coin is a coin made from two or more distinct components made from different alloys or metals which are then assembled into a single coin.
Thirdly the hardness of the alloy used to make a coin has NOTHING to do with a coin being clipped, if that were the case gold coins with clipped planchets would be as common as dirt because that's far softer than bronze or sterling silver or AlBr. Clipped planchets are a function of the planchet manufacturing process, nothing more, nothing less.
Fourthly (is that a word?), clipped planchets DO NOT have to have a neat edge. End of bar clips can have extremely ragged edges.
Fifthly, a real clip is actually quite easy to pick when compared with man made ones. You'd do well to educate yourself on how to do so. Here's an article that tells you pretty much everything you'd need to know:
http://www.australian-threepence.co...n-error.htmlFinally, you should think about the frequency of occurrence of clips in Australian coins and put some thought into why it has changed. Pre WW2 clips were very rare, from WW2 onwards they were much more common. In the decimal era they have become progressively less common as years have gone by. Why? Pre WW2 quality procedures were strict, in WW2 the mints in Australia, India, and the USA were very busy and QA (quality assurance) was poor. Post WW2 you mostly see clips on Perth copper where QA was clearly poorer than in Melbourne. 1951PL (London mint) clipped planchet coins are extremely scarce as the folks at
The Royal Mint really knew what they were doing.
Since decimals were introduced manufacturing processes have improved remarkably and in more than 6 years of looking this is the FIRST dollar clip I have seen. You almost never see clipped planchets of coins minted in the last 15 years or so. Funnily enough this pretty much coincides with the time that the RAM outsourced planchet manufacturing to Poongsan in Korea, who happen to be the biggest manufacturer of coin blanks in the world.

Good to hear
