Kosher Food Lead Seal, Plumba, Image & Found by James247Kent.
Found in Kent.
Kosher food seals with Hebrew letters on.
See Geoff Egan, No.356 Fig.47, 'Lead cloth seals and related items in the B.M. (B.M. Occasional Paper 93)'
From Rufus:- It's a 'plumba', a Kosher seal clamped to meat or poultry deemed fit for consumption after passing certain stringent tests. The characters are Hebrew. I have a couple myself, found on a field that must have seen the ritualised slaughter of animals for the London Jewish meat market in the 18th century.
An excellent article entitled 'Those Jewish Plumbas: All is Revealed!' can be found on page 1 of the March/April issue, No.82 of Leaden Tokens Telegraph by David Powell.
