This often happens, especially during the c1795-c1815 period and on smaller items, especially flatware. London, Exeter and Newcastle hallmarks all show this. It is suspected that it was an anti-fraud measure in that larger items would all have had a date letter and it was therefore obvious if a non-date-marked hallmark had been cut off and incorporated into a larger piece to avoid assay and/or duty payment.
