Reminds me of hoards found in Brittany (Vanne museum) that I've seen. Copper axes with a high quantity of lead, believed to be either for gift exchange or for votive rituals, hence the large amount of lead. Interesting that the channel islands were seen as a stopping off point between the coast of France and possibly places like Hengistbury Head which saw use from the Stone Age because of its natural port and its access to inland Britain up the river system. Your axes being later Bronze Age being socketed and looped.
These types of hoards are giving us a much better understanding of how people related to each other either side of the channel. Although it tends to be a 'them and us' situation these days (culturally different), back in the Bronze Age it was very different with trade and exchange thought to be much more common. What would be interesting would be to have the metal analysed to see where the bronze was sourced? Possibly north Wales, or even southern Ireland, or of course continental???
Well done again.
if there are no surprises they will expose the contents.
