Summener Seal, Found by Terry Mallinson.
Found in Essex, 5.2g.
Both sides have a central annulus with radiating lines looking like spokes of a wheel. Curved around the outside of this on one side is:- SUMME(N?)ER or maybe SUMME(R?)ER then some symbol followed by C---. The other side has S(U?)ISSE in a similar position. Summerer is a German name so perhaps a seal from the German speaking region of Switzerland?
