The valuation here is for the set of 5 graduated carved horn cups with applied sterling silver rims and shields on each. The silver is English hallmarked. The value will greatly depend on when these were made and the silversmith; that information can be gleaned from the hallmarks. Please add the requested clear, in-focus, close-up of the hallmarks stamped on the silver one of the cups. There should be a leopard's head to indicate it is English sterling, there may also be a monarch's head in profile for whom was ruling when this was produced, an additional mark in either a lion passant, anchor or tower will determine in which city this was assayed (also the city usually from where the silversmith is closely based), the letter initials are for the silversmith(s) and the letter in a cartouche is the year cipher. These were usually made during the first half of the 19th century in the early Victorian era, though some can be found as early as the 18th century Georgian era. The estimate is based on recent past auction sales of comparable horn and sterling nesting cups though could be narrowed down better with an image of the hallmarks.
