Die clashed Canberra

[echidna]

First die clashed Canberra I've seen.
Interesting obverse effect.
I'm wondering if the darker circle is associated with the clash or PMD ?

Gee that's a beauty and it's got a nice orb and just a nice coin all round echi, well done :good: but don't know what to make of the ring so maybe someone else may have seen a similar thing before.

[robbiegal]

yep
i have a one and only as well

Trout probably has about 50 but hasn't found them yet

[ausjack]

trout's at work so it might be a few days before he can post any pic's.

Nice one.

[trout]

I can't say that I have noticed this before, We are talking about the area in front of the Kings nose ??
This looks like a pretty new obverse die as there are no die cracks at all in the legends and I am not sure what caused the "halo" effect But it could be due to being stored with a smaller coin maybe a half penny??
I will have a look at some of my Canberra's when I get home But I can't recall seeing this before :ok:

Is that the same die clash florin that finished a week or so on fleabay? I bid on that coin higher than the grade deserved because of the die clash (but didn't win as obviously others also saw the clash).

Bare with me guys I have one of these what are we looking at with regards a die clash, new to this

[robbiegal]

the die clash is around the king's nose
it is bits and bobs the building from the reverse
going by memory of the one that I have, you need to turn the coin upside down to see it in context

Here's an overlay of Echi's coin images.

I probably needed to rotate one of them a couple of degrees but the overlay serves the purpose.

With a quick look you can see the reverse pattern on the obverse indicated by the arrow in the bottom pic.

[robbiegal]

wow
how do you do that?
i just found my coin and marks off the clash area for the new poster too
may as well still post them!
side by side - the clash on these coins ise almost identical

Nice one RG! That certainly confirms the error.

(I just used photostudio to flip the reverse then make a composite image of the two ...... the perfectionist in me wanted to play with getting the alignment exact, but spare time is not my friend at the moment :laugh2:).

Nice clash and good photoshop work Uni.

[echidna]

Thanks UNI for the overlay.
And thanks Robbie for posting your pics.

Do a little searching and you'll find several die clash threads. It happens fairly often.

Clashes occur when a press misfeeds and there is no planchet between the dies when they strike. The dies hit each other, and part of the design transfers. Because the design is cut into the die, so the high points on the coin are the low points on the die, it is protected from damage. The field, however, is the surface of the die, and so the edges of the design are the bits that transfer onto the opposing die's field.

"Why doesn't the entire design transfer?", I hear you ask. Well, it would if the dies were absolutely perfectly aligned. But there is a tiny bit of leeway when dies are inserted into the press, and they may be sitting very slightly angled. You would never notice this on a coin (well, unless the angle was hugely off, but that's another matter). But even a tiny angle is enough for one part of the dies to clash and not another.

Also, depending on the relative hardness of the two dies, the design may transfer onto one or both dies. The 5¢ I posted recently shows a clash on both sides for instance.
