Vintage 925 Sterling Silver Industria Peruana Hammered Trinket Dish 4 x 2.5 For Sale

This small dish came from my in law's estate along with several other sterling items. I do not know its age or if the piece was used. It has been in covered storage for many years.
The dish measures 3 7/8" x 2.5" and the ends of the dish are .5" high. It weighs 22 grams.
Delicately hammered pattern makes this an interesting piece.
