PPH and I picked this up from Wynyard coins on Thursday of last week. It was being sold as double struck. I am pretty sure I see evidence of 5 strikes though. Two with the coin in the original position (rotating between the first and second strike) and then three more after the coin had moved about 6-7mm.
It's a nice glossy brown UNC with an unfortunate rim ding on the obverse.

nice :drool:
Here's a close up image of the reverse showing clear evidence of the first and second strikes. The raised parts of the letters (that look a bit like cuds) are the leftovers of the first strike. The second strike formed the top parts of the letters that remain.

And here's a close up image of the lettering on the obverse. You can clearly see three steps showing evidence of three separate strikes after the first two. Making a total of 5 strikes.

Thanks AC. It's a pretty cool coin.
Wow Mark!
Great pics and notations. I really like the triple pic.
I should be working but I am still thinking about this. I think it may have only been struck 4 times. On the second detail picture I am pretty sure strike 4 and 5 are actually the same strike. Perhaps emu666 could chime in here with what he thinks?
Regardless, a quite unique coin.! Thanks for sharing.!! :yahoo:

I tend to agree with 5 strikes on this coin.
You can see the first 2 strikes by the way the denticals are doubled and the "ELIZ" definitely looks triple stuck to me.
What I find really interesting is the Queens Portrait seems to be unaffected.
A most interesting coin Mark :good: :yahoo:
Stop teasing or just give it to me, I know ya wonna :laugh2: Yeah it's pretty cool and I like the colour but could be just a little darker :winkextra: I am going to make a little bed for my babies so I can tuck them in at night and tell them how much I love them just like someone else does..my precious babies :angel:
One can tell, AJ is back and firing on all cylinders............
So sorry for going :off_topic: Mark and I should have put this in the thank you thread sorry, but I'm not quite there yet GS but getting there mate as I still have to get rid of it :( but you's can thank AC for helping with my recovery 'cause she's had her own troubles but still had time for me to bitch at her and I thank you so very much little mate..a real heart of gold :hi: so if anyone has a go at me little mate look out 'cause there'll be hell to pay..and a quick thanks to all who called and emailed as these little things help when we're a bit down :friends:
Now back to your usually scheduled program sorry :)
I think there's 5 Mark, like you said..first two then looks to be three more :good:
The obverse Strike 2 appears to me to be suffering
"Mechanical Doubling" rather than multiple strikes.
Either way a very nice example of a Double Strike.
Definitely firing on all cylinders........Whoopee.......
Um, oops, sorry, nice half penny error there.

Sounds good to me. The width of each letter should be the same on each strike. The obverse shows the classic terraced look due to the hammer die scraping across the design on retraction .
oh I see how it works now, it strikes and then bounces across so it's not really a true strike as such..thank team
Yes AJ. That's a good way of describing it. It is seen often on Melbourne Mint pennies of the late 1940s to early 1950s (the so called double dates or re-engraved dates; which of course they are not).
Cool thanks emu, it seems like the mints go through different stages of lack of quality control from time to time as I have been doing a lot of decimal noodling and when I start I seperate them into the years and it's here where you see a few things like low mintage or years where they pumped that many out it's not funny and how when we find an error there's usually a few around a few eg's are the bubbles and common cuds like rabbit ears etc and when looking at the years you can see that the early coins had more effort put in and better quality control when you compare the amount of errors and just the look of the older coins as a lot have a lot better detail..I want a job a the mint :)

Given that the doubling is present on almost all the legends on both sides of the coin and all show the same degree of rotation I'd contend that this absolutely is not strike doubling. The coin has rotated around the center point of the coin in between strikes.
The lettering also shows the characteristic spidery and thinned appearance of every multiple struck coin I've ever seen.
now I'm lost..thanks Mark :)
OK here's a detailed image of the AUS and the HAL off of the reverse of the coin. Obviously the AUS is on the top half of the coin and the HAL is from the bottom half of the coin. If the coin rotated clockwise between strikes you'd expect the doubling to the RIGHT of the last strike on the top of the coin and the LEFT of the last strike on the bottom of the coin. And that's exactly what we're seeing here.

Nope. Nothing. That coin is likely to remain a mystery.
poop, I wanted to know anything about that one :( There's some very strange things going on in our mints :dodgy:
