The description of this error is quite ridiculous but a friend has asked me about this coin?
To my inexperienced eye I suspect PMD. Can anyone please clarify what has happened to this coin?
Many thanks.
I agree with your assumption PMD :ok:
At first glance you'd say partial collar but the reeding shouldn't be on the "fat" part of the coin if that was the case. There are some circumstances I can think of that could result in a real error that looks like that (namely being struck once, being partially released from the collar and being struck again). The reverse is certainly exceptionally well struck and in great condition.
I'd like to put it on some scales and measure the small and large diameters before I'd say with 100% certainty that it's PMD. That being said I'd probably say there's an 80% chance it's PMD.

Most of that info is in the description:
QuoteAustralian 1984 Mule/Error coin. This dollar coin appears to have been with 2 different sized dies.
Reverse has the regular 25mm diameter, while the obverse is 1mm narrower at 24mm. Is possible that the obverse was struck with the die from the $200 dollar coins (which were 24mm in diameter), or the ten cent coin (23.6mm diameter)
There is faint interrupted reeding evident on the "obverse" side of the edge. The obverse edge also exhibits rim cuds at every reeding point. Weight is as per the regular dollar.
Composition: 92% Copper, 6% Aluminium, 2% Nickel
Weight: 9g
Condition: Lightly circulated
My two bobs worth ....
I think PMD. Someone has pushed a smaller collar (like a piece of pipe) over it with a press. If it was any other coin's collar it would not have the remains of the reeding, nor the so called cudding.

OK. Given that he says that the smaller side is under 25mm I'll go ahead and call this one PMD. Probably had the edge machined off.

:agreed:
Just another manufactured "Error" coin.
Add "Mule" to the description and ALL the morons come out and bid on this type of thing :dash1:
