1981 Australian 50 cent coin

 The heading in your catalogue  is not correct, it has Royal wedding Queen Elizabeth. When it should read Prince of Wales and Lady Diana Spencer.  Keep up the good work.    Bob

 No - it is correct!
Elizabeth II is in title as she is on obverse.
Wedding is in title as that is on reverse.

Maybe I reword from Wedding to something else though. Thanks.  

P.S. I searched  1981 wedding  and most have Royal Wedding in title, so I put in a request to change it to that.
 This is that search, and all also have Elizabeth II in title ...

 I requested two United Kingdom titles to be changed as well.
