There does seem to be a large difference between the 2 coins...
It appears that the OPs coin is a fair bit larger diameter than Mark's coin - based on the edge of Mark's coin just touching the tip of 'A' in Australia and cutting through 'Elizabeth'.
Compare those parts of the design on the OP's coin....

The OP's coin looks quite genuine too Trout.
I honestly have my doubts about the "OP's" coin. There is absolutely NO distortion of the design on both sides as would be expected for an undersized planchet. I imagine that the pressure would be set higher on the 50 cent press than the 20 cent press due to the larger surface area of the coins to be minted. I would expect some metal flow effect to be apparent because the planchet wouldn't have a collar to restrict it from spreading. None of this is apparent on the op's coin  |

Yeah,I'm 50/50 on both coins shown but don't know enough about minting processes to have a firm opinion.The only thing I can say is the only 2 examples I've seen of this error(back in the 1970's) is both strikes on the smaller planchet were off centre. |

Do you have access to a scanner?
A scanner would remove lots of possible problems with using a camera (eg focus, lighting, shaking etc)

There is clear fishtailing all over that coin which is a 100% indicator of unconstrained metal flow. Look at the bottom of the ELI of Elizabeth. The weight is spot on. The rim is formed exactly as you'd expect if the planchet was offset in the die when it was struck. And it's thinner than a 20c too. All indicators of a genuine error. Plus these sorts of errors are quite well known, and while not common, they do come up from time to time.
As to the coin being a larger diameter than mine...that's obviously explained by my coin having a lower striking pressure than the OP's. That's further backed up by his being beautifully struck up and mine showing a lot of weakness.
I admire your caution with calling this coin an error but I can assure you it's quite real. I'd swap it for mine in a heartbeat.

Great scans! I really like the 9 o'clock to 1 o'clock rim on the obverse, really impressive with the curves etc. Where did you happen to come by this coin d&w and the $2 error also? They are both great errors. btw:  to CCF! |

You are certainly lucky to have found both in your change. Neither coin appears to have any significant circulation wear. Top stuff! |
