I came across a pair of old spoons made from what looks like brass or similar copper alloy (not Dirigold) in a design that is very common with Swedish spoons of the late 1700 - early 1800. The exact alloy is unknown to me. Both spoons have strange marks on the back of their necks that distantly resemble worn out assay marks. I am puzzled and would like to know what other members of this forum know or think about the purpose of such marks. Thanks.
