Two Pictish Hoards: Norrie's Law and St. Ninnian's Isle
Hoard from Norries' Law, near Fife, 6th or 7th century, consisting mostly of hack silver. This was found in 1819 by workmen who spirited away much of it before the landowner found out what was going on. So some of the silver was probably melted down and re-used, which is appropriate in a way because that is what hack silver was for.
One of the fascinating things about this hoard is the pairs of objects, one of which is old and worn, the other new; presumably the new is a copy of the old. This, combined with the large amount of hack silver, makes this look like the contents of a silversmith's workshop.
Notice the two brooches, one old when it went the ground, the other new.
