Martin will be very pleased to know that I got my first New Zealand 2008 20c. coin in change at the Metro New World here in Wellington late this afternoon.

Thanks, Aidan.  Our friend David beat you by a few days :-)  I wasn't expecting to see these in circulation for some time, although it's true that the Reserve Bank often releases lots of coins into circulation shortly before Christmas, so many of the stockpiled issues might be starting to turn up now.  Keep your eyes peeled for a 2007 10c, the circulating variety!

I received a nice shiny $1 today, but it wasn't a 2008 but a 2005, I think the first I've seen of that year, in any case, even though they've been out for a while.  Problem is, I don't actually use coins all that much :-(

Could anyone please comment on this minor fault on a NZ 20c 2008

Bubbling of the metal near the ZA of Elizabeth and the A has faded into the background.

To a collector would you consider this of any value?

Thanks

Hard to judge, even from such a good picture. My first impression is that the coin has been just a bit too close to an acid that reacted with the metal. I have also seen similar effects from dies that had been cleaned at the mint with a cleaning agent that had not been completely removed.

This coin would have extra value only to people who collect such problem coins. The trick is to find them.

Possibly the effect of the die rusting, with the pits left behind after an attempt to polish it out.

Error coins are interesting but the market is very variable.

[BC Numismatics]

Tony,
  I think that is error is caused by a fault with the plating process,not due to a rusty die.

The Royal Canadian Mint,Winnipeg have been striking New Zealand's coins since 2006,unless,they were struck at the Royal Australian Mint by officials who received training at the Royal Canadian Mint.

If plating goes wrong it usually blisters or bubbles from underneath (i.e. something happening in the layer where steel and plating meet). Nothing will go wrong/develop just at the top surface later. Any imperfections on the top surface would be flattened totally at the instant of striking. Happenings under the plating could make the plating lift after striking.

I have seen small bubbles on a few of the new design GB 1p coins (one or two bubbles per coin). But I have only seen this one copper-plated-steel coins with as much bubbling as seen on this 2p that I have likely had for more than 10 years. There is something similar to be seen on the other side of this 2p but it is not at all as dramatic. The bubbling has not increased over the years - but one day I can check that by finding the photo I did of the piece about 10 years ago. RCM may apply plating in a different manner - but not too differently as far as what could/can go wrong is concerned.

thanks Mr Paul Baker

Errors and faults are quite "in vogue" in New Zealand at the moment - check these various threads at the NZCCA forum for interest:

Thanks everyone for your comments.

It seems like this might be a unique fault.

Many thanks
Azzaro

[BC Numismatics]

Azzaro,
  I don't agree with you there about it being unique.

There is a possibility of other coins having a similar fault.

Aidan.

Thanks Aiden - yes understand what you say.

I was basing my thought in that if the same plating fault occurred it could be
in an entirely different area or of a different size, etc. Meaning the fault would
be unique in itself, whereas for example cud is often seen in the same place on the coin.

Azzaro,
   These faults can also be the result of chipping from the dies,as the dies are striking thousands of coins per minute.Each pair of dies need to be replaced after they've struck around 100,000 coins.

Chipped die coins produce a different effect.

Azarro, there is some confusion as to whether the dots are intaglio or relief. Can you clear up that point?

Hello Peter
Definitely relief - they are raised off the surface - not pitted

Also, any idea why the top part of the A would appear to flatten out?

Thanks - Azzaro

[translateltd]

Design elements can become flattened as a result of oil residues on the dies, for instance - there have been some quite interesting examples affecting the 2008 $1 coin, one of which had an entire "I" missing from the Queen's titles, making her look like Elizabeth I, at least in name!  The same coin also had a weak 2 in the date, presumably caused by the same process.
