From Tudor shanked balls to gilt livery buttons — small, common, datable.
Metal buttons become common finds from the 16th century. Early ones are solid or hollow-cast with an integral shank; the 18th century brings large flat discs, often gilded and sometimes engraved; the 19th adds stamped two-piece buttons with makers' backmarks, plus uniform and livery buttons with crests and regimental devices.
Turn it over first — backmarks like 'TREBLE GILT' or a maker's name and town can date a button within decades. The shank type (cast integral, soldered wire loop, stamped plate) is a good period clue, as is overall construction: one-piece versus two-piece stamped shells.
Uniform buttons reward research: a regimental number or corporate crest can tie a field to a documented presence. Record diameter, construction, backmark text verbatim, and any gilding traces — and photograph front and back with equal care.
