Hello Everyone,
it's been quite a while since I last visited this site, I collect mainly US flying Eagle and Indian cent varieties, but I became interested years ago in the Australian penny, been an overseas member of the Australian Numismatic Association for about 10 years now. I hope you don't mind me jumping in here, it sure is a great place to learn a little about some coinage I'm not real familiar with.
I'm not really sure of the striking of the penny, but is it possible to have doubling on only the L and I of Australia?
If you wouldn't mind viewing my pic I would certainly appreciate any information or opinion you might have.

Thanks,

I think so. I'm not all that familiar with doubling but I think I read somewhere that slight rotations of the die will be more apparent near to the edges.

It is not uncommon to there to be doubling on one or two letters or numbers only.I checked my Rennick's guide, but this example is unlisted. Not sure if it is common, or just unlisted.

Thanks for the help, I have a copy of Rennick's Australian Pre-Decimal Coin Varieties and Rennick's Coin and Banknote values. I'm still a little confused on the grading of Australian coinage, but I'm working on that. It takes me quite a while to go over a coin, I'm not familiar with some of the terms,mint mark, and dot locations. It will all come to me as I attempt to identify and grade the coins I now have. I'm sure I will learn a lot from reading this forum, and once again thank you for your help.


Dave

If you can take decent photos then why not have a go at photographing some of your coins and posting them in the Australian grading sub forum.

I will certainly do that, I am in the process of reviewing the coins I have already posted to my website, I am sure most are incorrectly graded, much tighter standards for the Australian system. I have two of the 1962 Double Nose variety, I personally think that is one of the most fantastic varieties ever minted, I understand it is pretty common, sure is a neat coin.

Thanks for the advise,

Dave

That sure is a great looking coin, now in the edition of Renniks I have (2005) it only lists a "quad die doubling 4 points not 3" and another as " Deformed nose-various reasons"
(4 not 3) not sure what that refers to, how many different variations are there.
I'm sure quite a bit has been added since 2005 so I guess I better update my research materials.
I've always had an interest in US cent die cracks, collected a lot in the Indian cent series, but the Australian penny it seems has no equal when it comes to die cracks, lamination errors, or filled dies. I have a lot to keep me busy.

Thanks for the pic,

Dave

Thought I'd add this one, on US coinage I would call this Machine Doubling, not sure if it is the same for Australian coinage.

Robster,
You certainly have some fine coins in your collection, I have a lot to learn about the Australian coining process.
I am just fascinated by all the different type errors and the magnitude at which they occur.
I've just started the Half Penny found two nice ones out of the first three.

Would just like to ask a quick question here, I have searched the forum for discussions on amount of strikes per die for the pre-decimal Penny and Half Penny. I am just completely amazed by the amount of damage that shows on these coins. I assume most is caused by the hardness of the bronze rather than some type of die manufacturing problem.
Does anyone have an estimate of strikes one would get out of a set of dies? I picked up a few Australian pennies real cheap from a dealer who has some but doesn't know much about them, out of 20 coins, 8 had some type of doubling or die cracks, that's almost 50%. That seems a little high to me, but again, I know very little about the dies and die making of Australian coins.

Perhaps the person who owned those coins previously had a penchant for error coins. Certainly wouldn't see such a high percentage in a normal group of pennies.! As far as number of strikes I am not sure but someone will provide the info. soon.!!
