Help Identifying the error #2

[EgCollector]

To continue with coins that i think may have an error IMO  .

The rim of this coin doesnt seem to be of uniform thickness, so;

Is this an error?
What is the error name?
Does this increase the coin value?

Thanks for your help

There is a name for this, but I can't remember what it is
I don't think it is valuable.

I'd call it a slightly off centre strike.  Not really any extra value in Australia, too many of them around.

Thanks for the link , I am quite sure that this wont increase the value, but is it considered an error and if so what is its name and what caused it?

Please pardon my many questions

It is simply an off-centre die.  Yes, you could consider it an error, but it is probably within the mint's specification tolerances.  The technician (?) would probably note the off-centre and adjust the machinery accordingly.  Interesting, but of little value.

Thanks Yass 

So it is an error
The error name is off-center die
it adds no value to the coin

Thank you very much to all of you

It's probably a mis-aligned die. The striking  die wasn't properly centered over the anvil die. It's very common.

Amr, this is what I was trying to think of the other day, but could not remember what it was called. longnine009 hit the nail right on the head!

So it is an error
The error name is mis-aligned die not off-center die
it adds no value to the coin
