I have 2 20 cent Australian coins that are double tailed! There is no side with Queen Elizabeth 2 or the date, just two sides with the Platypus. My father-in-law drives a food truck and most transactions are paid using coins and both were randomly paid to him without even noticing until later that night, as he collects foreign/rare coins and checks his coins avidly. I am willing to provide numerous photographic proof of these coins and am in process of having them certified by a coin collector and/or banking institution? Could someone please let me know if this is the correct avenue for me to have these coins verified as legitimate Australian currency, and to establish a way to get a valuation? Any advice and/or enquiries would be welcomed thank you.

I have never heard of a genuine double heads or double tails coin. They are always refered to as a Magicians coin and they are produced after the coin was minted making it technically a damaged coin. |

Please post a clear photo of each side plus one of the edge. Sounds like it may be a Magicians coin but will need photos . |

I can take some photos, but tell me how do I get both sides to be in pic at once, so as it's certain that it's not just pics of the same Platypus? I can do this in morning, but want it to be a legit pic

You can hold it in front of a mirror and shoot at an angle but please take an individual photo of each side as well.

first guess would be a Magicians coin. To have the same side on both sides of the coin, is almost impossible. You would have to have 2 obverse, or two reverse dies, in the same press. and I don't think that is possible to do. |

To have two dies with the anvil and hammer die having the same design for the same year I think is impossible (at least to my knowledge).

There have been a handful of genuine double-headed/double-tailed Australian coins but most are likely to have been smuggled from the mint and the double-headed 2007 5c piece is probably the only one that has been found in circulation.
Get the weight anyway - if it is a hollowed out/magician's coin then the weight will likely be off.

I notice that several of the posters (Canadian) have dismissed this as virtually impossible. That might be bias showing as I know that US mints (and Canadian as well?) have the presses set up to make inserting the obverse and reverse dies only possible one way. Australian presses are not set up that way and there are a number of known examples of genuine double heads or tails (such as the 5 cent coin of 2007 or the 1957 penny). Markn (Purple Penny) also mentioned some time back about a slabbed (ANACS) double tailed 2 cent coin so even the TPGs have handled then

If there is a genuine example of a double heads or tails coin, I simply have not seen one. I don't dismiss that it's possible, I'm not aware of the minting process for all world coins. To me it does not make sense that when producing the dies to have hubs for both the anvil and hammer die with both reverse and obverse hubs. If they do that elsewhere I don't know about it. Just giving my 2 cents as iv never seen or heard of a real example in Canada and the USA. I'd like to see an authenticated double header or tails coin.

@nealeffendi I haven't seen the 1957 penny - when did it last sell?

There was one in an auction about 15 years back (Status I think). Went for about $5000 if my memory serves me correctly and the catalogue mentioned that it was one of 2 known. with that few it was either a stuff up that was quickly spotted and the batch scrapped (but somehow a couple were missed) or it was done on the sly and smuggled out. It wasn't Unc so not done on the sly to sell to the few collectors back then so maybe if done on the sly it was for use in 2 Up?
