Impossible to date with any accuracy, but most likely 1870s-1880s. This is a guess based on the relatively low pattern number. Britannia Metal was in use as a base for electroplating right from the start of electroplating c1850 so no real clues there.

Thanks so much for your response. I had been guessing—from the clarity and regularity of the impressions—that they were mid-20th century.
