So I have done some looking at errors on this forum over a few weeks. The die crack strikes seem to leave a ridge of metal on the surface of the coin. Maybe what I have posted is some sort of laminating. Surely it is not PMD? I have a 2012 copy of Greg McDonald's Guide to Australian Coins and Banknotes coming but I do not know what it will tell me as yet. Thanks to awildeheart info I was able to find that ebay seller. 1st thing I have ever purchased off ebay. Quote:Hi, I just paid $15.50 (Buy It Now, includes postage) for a new 2012 McDonalds on ebay. Seemed like a good price after surfing the net for quite a while. If anyone wants the ebay seller ID I bought it from, contact me and I'll pass on the info. Edited by kg5

Dont expect to get any information regarding errors from maccas. It is merely a catalgue of all coins and their prices. It includes a few well known arieties but often the information is very brief and a little disapointing.

Thanks for the warning enworb!
Is there an Australian Penny reference book on errors?
Or are there just heaps of one off error that are called a lamination etc?
Are there many constant striking errors. Maybe a cracked die would be constant. But my extra question is. Are the cracked dies used long enough to have a constant striking error?

Die cracks can usually be seen on multiple coins. There are several that are very well known, others that are not. Die cracks are important diagnostic tool used to identify genuine 1923 halfpennies. Not all genuine coins have them but many do. My two favourite well known die cracks on copper coins are the 1926 1/2d crescent shaped obverse crack and 1964 Perth 1d Reverse die crack from rim to rim. I know robster collects a lot of die cracks I'm sure he could tell you about different cracks that are easily found on multiple coins. Die rotations and clashes are also often replicated on multiple coins, as are some Cuds. Most other types of errors are one of sort of things. The lamination for example is caused by a fault in the individual planchet rather than the die. Whilst there are books out there that attempt to reference all predecimal errors they are really comprehensive. Renniks have a guide byt Fred Lever I'm fairly sure. I cant remember the exact name but someone will. |

Hi kg5, I have found the Rennicks pre decimal coin varieties by Ian McConnelly most helpful in identifying die cracks for all early coins.! While not everybody's cup of tea I was fortunate enough to have a gathered a great deal back in the 60's when I was a kid.!
With the help of my Dad and a family friend I now realize I was a fervent 'noodler'. When I reignited my interest in my coin collection 12 months ago I soon realized I had an abnormally high percentage and slowly recalled being the designated "picker" at the end of the table.! (Remember it was 45 years ago.)
The end result is I now have several hundred coins spread through all denominations which also gives me a great opportunity to hone my skills in 'coin photography'.
Interestingly I do not seem to have any 1938 Penny's with errors or cracks but there are 16 different errors noted in the aforementioned book.! Hoping eventually to trade any multiples with like minded people so we can all expand our collections.!! Cheers.!

I am very blessed some years ago my adult children gave me a digital magnifier that can take image hooked up by a cable to a port to a large screen computer and the system can only be use as a magnifier. I will have to run the programme on this computer so I can post images from it. By using a clear plastic page on top of the coins will bring them to life. So having the ref books is going to be very much needed to get the most out of my time. I am a chronic bulk collector and I have been working the auction houses for about 15 years now. As I had a full on accident and my wife steered me in this direction of auction houses to give me a quality of life. My wife always wanted to go back to uni and extend her knowledge after the kids grow up. Well selling on ebay has payed for that to happen. Last year and this one ebay has payed for everything. Even with all the work she has to do and loves it she still helps with the ebay business. Coins is a new frontier for me and I can use my experience at the auction houses that know me from many years of business. So when I ask them for info on pre-dec coins I can trust the personalised extra info about a bulk coin lots for noodling. So I might be a newbie but I have a very compatible back ground for coins. Noodling from Banks has got me big time. It makes a lot of sense. In May I plan to get into that. It is nice to be able to pay for my wife's and youngest adult daughter's education from selling on ebay. And also pay for bulk coin lots. |

Most Geo V pennies with dies prepared outside of London seemed to develop die cracks and those die cracks can be found to grow in size and number as the die deteriorates. Sometimes you can use this to identify early and late die stage coins and to determine when a die pair has a change in one of the dies. Roo pennies have fewer die cracks (but still not rare). Your roo has a crack in the coin (lamination) not a die crack. Flaw is only small so fairly common. To get to  you need a BIG lamination error. There isn't a good error book out there. Both Ians and Freds books are fine for noobs but not for seasoned collectors. |
