don't understand what we are looking at in the pics, I see two coins and don't know what you are trying to show us. Pics of a 2 headed coin is almost going to be impossible to pull off in my opinion, I mean heck you can just take two pictures of the same side for all anyone else would know. I can tell you the way the minting process is in the US this is impossible, I am not sure about how the minting process works in Australia to say this is true there or not

mostly I want people to see the qulity both sides, I can assure you I'm not trying to trick anyone I'm not three. also if any one has good knowledge of the minting process they could share some light as to weather this is possible. Maybey someone has already seen an example of this?

Nelid,
Folks can be very clever in making these. One thing you should try is to see if it weighs the same as a normal 5 cent coin, or not. If not is likely some kind of fake. Also, look very closely with a magnifying glass for a joint on the rim, or where the faces of the coin meet the rim.

I don't know what it would be worth but I imagine it would be a lot. However, everyone will be very skeptical of the coin.

We're not saying you're trying to trick anyone, but we are saying it's highly likely that you've been tricked.

I assume it's the coin on the left, with "2007" date on both sides? A different date on the two sides would be a clear indication that it's not a genuine "mint error".

It's impossible in the normal course of mint operations to make a two-headed coin "accidentally", because the "heads" dies are differently shaped to the "tails" dies, and can't be "accidentally" mixed up when being inserted into the coin press. A double-headed coin can only be made "experimentally" by mint workers on a special press set up for that purpose. No such "experiments" can be officially released to the public; they're all supposed to be either destroyed or kept by the Mint. Any found in public hands would be considered stolen property, smuggled out of the mint by a mint-worker hoping for some "extra profit".

There are very, very few genuine, certifiable two-headed coins: two examples of a 50 from 1977 are known; when one was put on the market in 1984, it was confiscated by the Federal Police as stolen mint property. I believe both specimens now reside in the Mint Collection.

I haven't heard of any genuine examples of two-headed coins from recent years. Most of the ones you see on eBay or elsewhere have been "manufactured" as a trick coin. The usual way is to grind down one coin until it's wafer-thin, then grind out a second coin to make a bowl-shape, just big enough to insert the wafer-thin first coin into. When done expertly, it can be very difficult to detect the seam. It's safest to assume that this is in fact what you have, unless we can see very detailed pics of both sides of the coin, as well as the edge. As rggoodie implied, the weight of such a "machined" coin is often wrong. It will also probably "sound" wrong when spun or dropped.

I should point out at this point that anyone making such a "trick coin" here in Australia would be deliberately damaging or mutilating Her Majesty's Australian coinage, which is also illegal and people should be discouraged from doing this to current Australian coinage (though I doubt the Feds would be too interested in prosecuting anyone for mutilating two 5 pieces).

Does anyone have the last Downies auction catalogue? I think there was a genuine double sided coin listed. Not sure if it was Australian though.

Neild, As John Paul stated, the process for producing two-headed or two-tailed novelty coins is very good nowadays, and sometimes the deception is hard to detect. Today it is done using a metal lathe and leaves no seam on the coins edge.

First, I recommend doing a little research, if this is a known "mule" error then you might have something, but I don't recall hearing anything about a two headed Australian mule error. It is very unlikely that your coin is a genuine Mint error. We routinely find these "flippers" in change here in the USA. They are usually purchased to cheat on the coin flip.

I suggest taking several 5 Cent pieces and dropping them onto a hard surface one at a time. Listen closely to the sound they make. Now drop the two headed coin and see what that sounds like. If genuine, it should sound the same, but I suspect it will have a dull sound instead. This is not 100%, but it's a good indicator. Also try to check the coins alignment, the man made "flippers" are rarely properly lined up.

Bottom line is if you haven't seen and read up on this error happening on the Australia 5 Cent piece, then odds are you found a man made novelty piece worth only a couple bucks. Don't feel bad, because many people get fooled by these coins every year. ~ Jim

I thought the dies for the obv and rev were different! As in the die for obverses wouldn't fit in the reverse die machine.

Thanks for all your help , I understand the chances are slim however I still plan on making some further investigations. In a couple of days a mate of mine is going to do industrial crack testing on it to see if we can find a join. Then after that it's off to the scales .
Also some of my thoughts 1.I found this in circulation nothing lost gained. 2 I have trouble thinking anyone would go to so much trouble for a five cent but maybe I'm wrong
