Silver Repousse

I recently bough a set of six repousse serving bowls but can’t track down their provenance. The chop mark is difficult to read while the silver content would appear to be 850. Total weight for the six bowls is 450 grams (give or take… the scale I currently have access to is not terribly accurate) and each measures about 3.75 inches in diameter.

I’d greatly appreciate any information about its provenance and value.
