The Antiques and the Arts Online has an example of some old security nonsense:

A complete and authentic vampire killing kit — made around 1800 and complete with stakes, mirrors, a gun with silver bullets, crosses, a Bible, holy water, candles and even garlic, all housed in a American walnut case with a carved cross on top — attained $14,850 in the Jimmy Pippen estate sale by Stevens October 3–4 in the new Natchez Convention Center.

If it actually killed vampires it would be worth a lot more, just saying…
