Elizabeth II Ten Pence [επιλυμένο]

I may well be having a senior moment here, but I can't seem to find this ten pence coin in the catalogue. Dated 1983, 2nd portrait, large type. What am I missing?

Not issued for circulation; in sets only.
I guess enough were already in circulation, and they
just made some to keep issuing the year 1982 1983 1984 sets.
That 28.5mm is the large size, and 24.5mm nowadays.

Thanks Zac, that explains it.
