Description: | An incomplete large copper alloy ingot of uncertain date. The ingot has been formed in a sub-rectangular mould resulting in the flat 'top' of the ingot being narrower than the uneven base; the sides therefore are slightly bevelled as are the corners. While one end of the ingot is flat (from the mould edges) the other end is uneven and there is evidence that part of this end has been cut or sliced. One one long edge of the ingot there is a vertical linear indentation, possibly an intentional marker; there is a second similar indentation close to the edge of the possible cut. What may be a small patch of lead alloy adheres to the top; the ingot is very heavy however without analysis it is unclear whether or not the copper contains lead, which would increase its weight.Although this ingot was found in the same area as late third and fourth century coins, including a number of barbarous (contemporary copy) issues, Roman copper alloy ingots from Britain (specifically Wales) are 'bun' shaped, not rectangular like this example. Lead 'pig' ingots of Roman date are very similar in form however no copper alloy ingots of this form are known in Britain; some Spanish ingots are similar but no direct parallel for British examples could be found in preliminary research. The patina and findspot suggests a Roman date however without metallergical analysis the date range must remain broad; Roman to Post-medieval c. AD 43-1800.
