Atropos Antiques has dated this piece to the Before 1700 period.
These coffers are sometimes referred to as 'sword boxes' which is a somewhat glamorous title particularly taking into account that those who owned them could probably hardly afford cutlery, let alone swords!

It is more likely that these chests or coffers were made by their owners or possibly the local blacksmith or carpenter and were designed to house items of value and things likely to be consumed by rodents. Furniture, at this time was the preserve of the wealthy and most cottagers were in possession of a table, a bed, perhaps a food cupboard, a trestle or two and then, of course, the ubiquitous 'coffer' which would also serve as a seat.
So many of these have been 'carved up' as we say in the trade.
(i have known the odd antique dealer 'add' a bit of 'authenticity' to such pieces too!!

This coffer is very original. One feature that all from this age would have had is a pair of simple staple hinges. These are seldom still intact and this lid and carcase has the remains of it's staples still apparent. The hinges would eventually wear out and those present here are later, (1760) 'spade end hinges'. Locks were another casualty for obvious reasons and this chest bears a later but very period lock and hasp.

I commend this coffer as a clean and 'sleepy' example of good proportions and with an outstanding sheen and patina.
Unfussy and subtle it will add a good look to any period home.
