Hi All. Thanks for your interest. I'm not sure if the missing leg is a result of an issue with the die or maybe wear during circulation. That particular leg seems to be very subtle on most years so I guess it might be a result of either?
Anyway, here are a couple more that might be of interest? I have tried to get good pics but I think my lens might be scratched so apologies for the poor quality.
2011 - cannot see any hint of a leg on the one on the right no matter how I tilt the coin under light. The other one on the left has a faint leg?
I have also found these examples from 1998, 2008 and 2009. The 1998 doesn't show any signs of a leg regardless of how I tilt it under light but the other two show a very faint 'edge' of a leg under some angles.




Anyway, I am happy to include them in my "Odds and Sods" collection.
