Here's a bit of history about the 1847 Rogers Collection (from the web)
"Rogers is a recurrent name in American makers of coin, sterling and silverplate ware.There is a great confusion about the firms bearing this name. The number of companies using the Rogers name is countless. The men managing the various "Rogers" companies sometimes were linked by family relationships but often this was not the case.Lots of companies with this name were created, merged, separated in an endless succession of intertwined relationships.In 1862 Meriden Britannia Company bought the hollowware division, tools and dies of Rogers Brothers Mfg Co (incorporating Rogers, Smith & Co).The production of the '1847 Rogers Bros' line continued under the direction of William Rogers and in 1865 the plating shop was transferred from New Haven to Meriden and merged with Meriden Britannia Co in 1866.In 1898 Meriden Britannia Co and various other independent New England silversmiths joined themselves together to form the International Silver Co that became the world's largest manufacturer of silverware. Rogers 1847 became a trade mark of the new firm."
