Week 19, Lead cloth seals

I'd never heard of cloth seals before but I was presented with a box full, mostly made of lead, these tiny seals were used in Europe between 13th and 19th century to seal and identify sacks of goods and for quality control (wool, cloth etc). They would display the initials of the manufacturer, coat of arms of the city, date and other information. They are very small - similar size to a 5p piece.
