Not sure I understand the question: what's wrong with ".../2000"?

In the UK the current year date has been written in full since the
introduction in about 1907 of what became know as the "Leicester system"
of numbering - i.e. accession numbers in the form: ##/YEAR/EXT
(where ## is the sequence number for accessions in that year, and EXT is
the extension number for parts or items within that accession).
