The spoon has some perplexing marks.
The first mark seems to be a woman's head, faced left. Then there's the letter D, and then a rubbed mark, which is probably an 'M'. What's going on here? My first instinct was to think these were pseudo marks. However, the spoon is extremely thin - as if made from sterling silver by a smith, who didn't want to waste too much silver on a small spoon like this. I have no testing kit, but the metal looks and feels like sterling (it was polished after pictures 2 and 3 were taken). The three marks are quite rubbed - was there once a fourth one with a maker's mark? Are the three exisitng marks at all compatible? Help!
