I have a 2014 coin certified by NGC 2887541-002 which NGC claims cannot be added to the set KANGAROO SILVER DOLLARS 1990-DATE, COMPLETE INCLUDING VARIETIES and should be in a commemorative set., Why not as they don't say and there is no way to find out. Closest I can find it in is the Renniks australian coin catalog 2014 mob of roos 30th anniversary high relief. Page137. This looks exactly like it but it isn't high relief. Also 5822194-009, 4899300-002, 3948626-049, 2791561-015, 2791561-011 are all coins with the same design. So what is this coin. I'm I missing something or did NGC certify something wrong. Please help this coin collecting stuff is so confusing to a old lady. Thanks Also Ngc lists slots for five kangaroos in the above set in 2004
