Hi, I'm new so forgive me if I'm asking something silly or obvious. Is this a planchet error? Or something else? Or more likely, nothing at all! Image attached. [attachment=3679]

[Goldseeker]

It is what is commonly called "road kill".   Most probably fell out of someones pocket/purse and either has been run over by a vehicle or most probably mowed over with a lawn mower.

Sorry, it definitely isn't an error coin.

Current value $1.00.

Don't forget, there is no such thing as a stupid or silly question.

Got a pic done of the SA 20c, probably closer to 1 ish now than the  2 that  I initially thought. Was using  the hands on my digital clock at the time, it said 12:02 :angel:

Hmmm...I was just about to add this to my Decimal Upsets thread, when it sort of dawned on me that it's the Obv that is usually the side that rotates, so...that should mean that it's about 330° rotated.

Any comments?

My problem with this coin is that both sides appear to be rotated by the same amount, so in effect, they cancel each other out. When the IRB portrait is unrotated, the point underneath the queen's head usually points directly downwards, not down and to the right as Gnome has it. I think that if the obverse were held in this position, which I use as a reference for my own calculations, we would find that this coin isn't rotated at all. :ok:

G'day Nancy, just rechecked, still looks about the same to me.
I use the point of the crown as the point I check from, it's usually lined up nicely with the reverse.

Found another changeover $1 coin today. That makes 3 now.

A couple of interesting $2 coins have just turned up here.

My wife found this one in her change, brought it home and said it was a pity it had a dent on the bottom. Indeed, it does look like that with a quick glance but it is markings exactly corresponding with only one segment of the edge reeding -more pronounced on the obverse.
I am not sure what mechanism would cause this. Does anyone know?



A couple of days ago a teller at the bank asked me if I had seen a $2 coin with a double edge? I immediately thought mule (just kidding) probably an offset strike.
Today she showed it to me and it is a definite, well centered double rim on the obverse. Size looks a little wrong so I measured it and used the above mentioned coin as a comparison;
                Double rim       2016 $2
Diameter     20.82mm     20.50mm
Thickness     2.68mm      2.84mm
Mass                6.43g         6.60g

Could it be a wrong planchet? Checked edge more closely (it is a well worn coin) and reeding is there faintly. Also faintly a tiny ridge along the obverse edge -looks like a collar error but coin seems a little too light!

Theories anyone?



I will try and get some edge photos, in the daylight, tomorrow.

I don't know much about the second coin, but the "dent" on the first coin is something I've seen several times before. My records show that I found one on a Standard 2014 $2 coin in August last year, but I never got around to asking anyone what caused it. I'm very sure that these "dents" are made by the mint, but I'm not sure how or why. I wouldn't complain about getting one on a changeover coin, because I've only seen this phenomenon 1-3 times on 13800 $2 coins, and I've never seen it on a commemorative one. I suspect it would sell for $5-$10 on eBay. :good:
BTW my one is also at the very bottom of the obverse underneath the queen, so it must be something to do with the way they hold the coins in the machines. Otherwise, it would appear on any part of the rim, and on any side of the coin, rather than in that specific location every single time. :ok:

Jeff, the bottom one is curious.

There seems to be quite a lot of flatening on the legend on both sides, so I'm wondering if it's been pressed? That could explain the increased diameter and reduced thickness. The under weight, not sure, but I fancy that I see some incidation of rotational marks in the fields, especially on the obverse. (but then again I fancy I see a lot of things, being a unicorn and all :laugh2: ).

[rollycoins]

I've got a few of those indents as well! They're actually fairly common. Seen quite a few more but stopped hanging on to them. There's only so much dough to go around :yahoo:

I've got two changeover $2 with the indents, 2 from 2015, 1 from 2014 and the 2008 just has a similar pattern going at the upper left quadrant. Not sure how they happen too, but just hung on to them as they looked interesting.

[Hercules]

I think the 2008 one is a different phenomenon to the others. Sometimes the die is titled slightly, leaving an extra rim around part of the edge, which appears to be the case with the 2008 one. However, there is no tilting on the others, so I find it interesting that these indents even occur, let alone in the same location.

[Nevol]

I've got some coins like this stashed somewhere, I believe I posted some images to see what possible explanations there could be.  

Don't remember anything plausible being put forward. I'll see if I can find the thread.  :angel:
Just finished trawling through all my threads and can't see where I might have put them, now to search by post. ......................

[JeffH]

Here are some photos of the ones I posted last night. I am with Nevol -plausible explanations would be nice. Maybe Fulvio might have an idea as he seems to be good with that sort of stuff. I wonder if the axial marks on the edge of the double rimmed one mean anything?

[Nevol]

Still can't locate any of my prior pics of this type of 'error' which leads me to conclude that I must have been dreaming about them.  

The closest I can find is post #28 in this thread:
https://www.australian-coins.net/showthread.php?tid=680&pid=8647#pid8647

..but my coin, $1 2001 CoF, is considerably different to those posted here.  In that post I concluded that it was PMD.

Hi Guys, the 1998 coin is probably from the "Someother" Mint in china.
There was a fair bit about  loads of fakes flooding the market at that time.
There was a bunch of articles in CAB, my mind has gone blank about exactly when but I did an article myself.
Naturally it was an offence to even hold one in your hand so I never wound up with any examples...ho ho.
You guys with better memories may recall all the hoo ha at the time I think the feds stepped in and cut the source off.
Probably jailed someone or shot someone to stop it.
Cheers, Fred.
