Interesting discussion. But, alas, no real conclusions. But I will have to live with it.
FYI - Just a little more info regarding this item:
Below is a full set of pictures.
As you can see the box is heavily embossed solid silver with a filigreed top.
Through the filigee, there is mother of pearl.
In the center is a small glass cover under which
was a small ceramic disk with a beautiful watercolor scene.
Unfortunately, the watercolor got ruined so I replaced it with a wedding picture of me and my wife.
The entire inside of the box is "gold" colored. Since it has never discolored or tarnished, I assume it is gold flashing.
The box's dimensions are: 2.5" x 2" x .75" and weighs 2t oz 2 dwt as shown.
The rubber feet were my addition to protect our table.
Note that the bottom of the box "buldges" out in the middle. That is where the hallmarks are.
Since this was carried in a pocket or purse and frequently placed on a table, the hallmarks got the most wear.
Other than the 3 hallmarks shown, there are no other marking anywhere on or inside of this box.

P.S. - The ground in these pictures is white and, of course, the box is silver except for the inside which is gold.
