Acts 19:19

Brought their books together, and burned them. There was real repentance, and they brought forth its fruits. These "books", alluded to by ancient writers, were manuscript volumes of charms, incantations, recipes for love philters, and other things of similar character.

They counted the price of them. If the "piece of silver" is the Attic drachma or Roman denarius, as is probable (about sixteen cents), the whole value would be about $8,000. These "books" had considerable money value on account of their rarity.
