hey all
Just curious, I have a australian (1999)10 cent piece with a backward 5 cent stamped on the queens head side.(it's only half the 5 cent piece, and it's backward)( you can see the 5 and one of the platapus's foot) Obviously, it's a rare piece....but how rare?

Hi XFISH, & welcome to the forum.  Can you post a picture of the coin. It sounds a bit like it's been 'manufactured' post mint by an enterprising person by smashing the 5˘ against the 10˘. I'm not an expert in this, but a picture will help the experts on this forum to decide what may have happened to the coin. life is a mystery to be lived not a problem to be solved

Hey It's has every detail of the 5c ,I highly doubt somebody could smash all the detail of the 5c piece on. so I think it's been made at the mint. It looks a bit messy where the coin doubles up. But where it doubles up, all the queens details are there with the 5c details on top.I'll post better photo's later in the week..... Image:  cc1.jpg5.8 KB Image: cc2.jpg5.1 KB Edited by XFISH

without clearer pictures, it looks like some we have seen before that were compressed together in a vice.
We need clearer pictures or to send you to one of the local coin shops
If you need the name of some of the Perth dealers just let us know

If it's backwards like you say, it's not a hard thing to do. First place a 5 cent coin on the 10 cent coin. Next, find a hammer. Third, use a massive amount of force to whack the hammer on top of the 5 cent coin to make it appear as a hammer job. Tada - a brand new hammered job coin, i.e. post mint damage. That is what I am thinking

I have to agree with the others. IMHO it is definitely a post mint product.

Check out this one on the US based auction site. Bought a few chuckles from the collectors there. 180222015069 |

I actually did some experiments a while a go with a sledgehammer and some coins... You'd be amazed how crisp an impression you can make with enough force (and 8kg sledgehammer weilds some force!!). The main problem with 'hammer-jobs' is 'spread'... To get a good impression you're going to have to use force which tends to 'spread' the coin. So even if you can control the force to keep the coin flat (ie, high pressure vice, indirect hammer strikes, etc) you then need to contain the sides of the coin. The only solution is some sort of collar, but that starts to complicate things.
Still, given time and a few hundred bucks (a nicely machined three part collar, brass to make some impression stamps with (could probably figure out how to do it with steel too), some sort of heating gear (smithing forge or something), hydralic press and a few dozen coins) I'm sure I could come up with stuff that would fool most ppl. It would be very strictly low run of course, due to the hassles of making good dies in hard materials. But there in lies the problem; you only want to make one or two, BUT the cost involved in set up makes it hard to make a profit!
BUT the bigest issue really is, its illegal! Even whacking a coin with a sledgehammer, or chopping them in half to check compositions and etc is illegal! Well for Australian Currency anyway!
