Hi all, I recently purchased a reasonably large lot of pennies and other coins, 1930 Australian penny was amongst them, how do I know if it's real?   Best Regards, |

Thanks for that, I have had a look at it and it seems like it's genuine, although it seems a bit shiny. Would anyone happen to know by looking at it's image if it's genuine?
And is there a place that can grade it or give me a certificate for it?

The best bet would be to take it to a dealer who specialise in rare coins.

If something appears to be too good to be true, it is.
How much did you pay for the lot of coins? We do not need to know the answer, but you certaily need to know what was the money you paid for that particular item only.
The Royal Australian Mint used to verify 1930 pennies, I had an Adelaide Pound verified many years ago, but I do not know if they still offer a verification service.
Take it to the most reputable coin dealer you can think of in Sydney, and they may be able to submit it to the Mint on your behalf. That is what I did.
Considering the possible importance of such a coin and knowing that very good forgerys abound, I personally would not like to offer my opinion from inspection on the screen.

Hi Titanium,
Your coin has a London Obverse & it appears to have a Birmingham Reverse,So i'd say it is a fake but I am far from an expert so if you can take it to a professional coin dealer,that would be your best course of action.

Here's a comparison of the date area. The OP's coin is the upper image. I think only 1 reverse die was used in 1930--correct?   Edited by DVCollector

Ah I see what you mean, I purchased it from someone selling a deceased estate, I did not pay much in comparison to the value of the penny, but it was included in a larger lot I purchased, so it could have been he did not notice it. (possibly another reason pointing it is not a genuine).
Of the others, there are some very high graded ones that are UNc, so I think I might take them to a coin dealer and get it checked. the 1925 & 1946 ones were checked and I was told they are fine. Thanks for the feedback though, much appreciated. I will list the other pennies dates later
(I also have a 1930 half penny UNc very high grade) Not sure if that is of much value though.
Regards.

UNC coins of this period will always generate interest in an auction.

The CAB (Coin & Banknote Magazine) has just published an article on Chinese fake 1930 pennies amongst other coins. Apparently they were made with spark eroded dies. The article shows you how to detect coins made with this sort of die.
I suggest anyone interested in this subject would be justified in buying this issue of the magazine for this article alone.
Other methods of manufacture of fake coins include:
Alteration of coins, lost wax investment casting, and explosive impact die manufacture.
It is essential that the collector knows of the existence of the various methods of the manufacture of fake coins, and results produced by each method of faking, in order to recognise the characteristic signs of each method of faking.
I just had a crown placed on a molar recently, and I was fascinated by the process. The implication of the manufacture of the crown and its obvious application to the manufacture of fake coins was obvious to me.
The dentist levelled the molar to the gum line, with just a limited dentine protection to the pulp underneath. He then scanned the stump of the tooth with a laser from three different directions, and so constructed a cyberspace model of the crown he proposed to make. The model was rotated on a computer screen, and finely modified to my personal requirements.
The cyberspace model then became the cutting instructions to machine a new crown out of a porcelain blank. I just stood in front of the milling machine with my hands in my pockets watching my new crown being milled with diamond cutting points.
That is how easily a new die for a coin can be made, with a laser optic profile model.
The new crown was glued onto the stump of my molar, and that was the end of the operation. The whole process took about 3/4 of an hour!

Its a fake, and not even a good one, no doubt Chinese in origin. Wasn't even copied from a 1930, but rather from a 1931-36 penny. The shape of the 0 in the date is wrong, the details are far too flat.
