Metal Detecting

Hi All
I found what I think is a lead ampulla on pasture on a permission in Essex. Approximately 4 to 5 inches down with a varied signal using my Vanquish 440.
Not sure what shrine this would have been from but more interested in the age . Could anyone help on dating it please?
Thanks in advance
Paul

These are an interesting little glimpse of history.

Medieval

They generally will date from 12thC to !5thC very difficult ascribe a date as you might imagine Cheers Eric
