lamination
A thin piece of metal that has nearly become detached from the surface of a coin. If this breaks off, an irregular hole or planchet flaw is left.
This is from the CCF glossary.

Thanks, latman, for clearing that up. So it's possible that this could be a lamination error? Are they rare errors?

Hi, Is the surface where the metal is missing from smooth or sorta jaggered/rough ? any chance of a photo of that surface ?

It's very smooth to the touch. However there are some very faint lines on it (maybe little scratches).

In that case I would lean toward it being post mint tampering,sanding or similar.

Even without seeing the coin its obviously a post mint altered coin,intentional or not
What is the date on this 50c Michell?

Mitchell: I have a number of Oz. ten cents (with the lyrebird reverse) that have laminated planchets. I fact, I have a couple of these where the coin has completely split into separate reverse and obverse pieces, both in 10c. and 20c. pieces. New Zealand coinage also suffered from this problem at the same time
Being also in Oz, (Brisbane), Sap would probably be familiar with this type of planchet defect. I have not seen a delaminated 50 cent coin, but it would not surprise me that they would exist. The fault would have occurred in the rolling of the strip prior to blanking. I am not familiar with the rolling process, perhaps it has to do with temperature control lacking, or impurities in the strip.
The delaminated Oz. coins that I do have were made in the early '70s.
As for the edge, I guess that being weaker at that point, a sliver for metal has just broken off in that location. The edge at that point is slightly irregular, and from looking at the picture on screen, that seems likely.

@ jonsopet
It was made in 1980
@sel_69l
Thanks for your information. At the edge, right around the part in question, it is slightly lighter than the rest of the coin. Could this have something to do with the lamination?
I've got some conflicting responses. I'll hold onto the coin for a while and try to get an expert to look at it in person.

Of course! I'll post it back on here when I find out. It may take a while though. I don't know any experts . |

If you have a coin shop near you, take it in and they should be able to tell you.

The closest coin shop is about 2 hours away from me. It's quite a drive for just one coin!

Mitchell send it by registered mail to that dealer but phone him first for arrangements.
Easy mate registered post and a phone call is cheaper than petrol

I'm going to be goin there in a couple of weeks to see some of the things they have and ask a couple of questions. I'll take the coin with me then and ask about it.
Thanks for the suggestion though.
