WelshAntiques has dated this Welsh Oak Coffer Bach to the 17th Century.
The detachable lid has a moulded edge and is fitted to the plain dovetailed box beneath by long wooden hinges; beneath a narrow moulding is a single drawer with circular brass handles above a deep base moulding which is raised on turned ball feet.

Wonderful original colour and surface patination.
(The iron lock plate is false, that is, there is no lock.
The rear feet are replacements.)

Carmarthenshire, west Wales, circa 1690.
The coffor bach was traditionally associated with marriage and went with the bride to her new home.
I think that this is probably the earliest example that I've ever come across - any earlier and it would simply be described as a box with a drawer and would not be of these proportions or have the same constructional details.
