I'll assume you're using a diku variant, as you haven't told us
what you are using. The rest is easy. Since you're probably using
vnums, just set the unique items to -N or something like that.

Store all unique items in a seperate file. Load the file when the
game boots. Save it when you shut down or make any changes to the
items. In the player file, just simply do something like:

UniqueItem        NumberOfItem

Piece of cake. (This assumes you use keyword/value pairs, which
I highly recommend over your typical diku-dump of values.) The
'NumberOfItem' would represent the number in the list. Each item
in the list would be the next highest available -N number. Thus,
the first one would be vnum -1, the second as -2, and so on.

Since they are unique, you just fully construct them/store
them in your unique item file, rather than reconstruct them
from a vnum/template.

That's probably the simplest way to handle it. (Unless you
just add a bit flag for "unique" and fully save/fully load
all data from player files, but then you still have to make
an index of them all ... so my suggestion is better than
that, or so I think.)
