Part of a silver seal-matrix. The matrix is circular and the face has a beaded border and background decoration of scrolling foliage. The central motif is a merchant's mark and described from the impression, it consists of the initials "AMB" ligated with a central staff extending upwards from the centre of the M. The staff is entwined with a letter "S" and at the top it descends on an angle to the left, forms a loop, then crosses the central line and terminates in a cross (+). Only the face of the matrix survives. On the reverse is a scar of broken metal suggesting that the handle was hollow and circular with the face perhaps soldered to it.

Diameter: 20.6mm

Thickness: 1.7mm

Weight: 3.77g

IOW-602EE7is a copper alloy seal matrix and has a similar style of merchant's mark and is of similar construction with a tubular handle (perhaps once holding a wooden shaft or handle) behind the matrix face.

Signet rings with this style of merchant's mark are also known, such as SWYOR-DB0A17 (2014 T348),which is fifteenth or sixteenth century in date.


As this object is likely to be more than 300 years old and it is made of silver, it appears to meet the requirements of the 1996 Treasure Act.
