File:1EF321. Post medieval silver seal matrix (FindID 224925).jpg

English: A silver seal matrix dating to the late 18th century, c.1775 AD. The handle of the matrix is hollow, oval and conical with a large suspension loop at the top. The loop is flat with an octagonal outer edge and a circular hole. The conical handle is decorated with concentric bands and has a longitudinal seam at one side. At the base the edge of the handle is flared out and roughly shaped into an oval. There is a hall mark at one side (the same side as the seam)comprising a left facing bust, a lion and the letter A. It does not include a town mark, but it has been suggested by Peter D. Spencer that the letter A corresponds to the letter for 1775 in London. Attached to the irregular rim is a separately applied sub-oval plate with reversed copperplate style initials of JL. in side an elongated octagonal frame. The method of construction suggests the components were separately and probably mass produced, with customers then able to select the handle style to go with the appropriate monogram.
