Vess's Counting Spectacles

Wire-framed spectacles worn by Mother Vess, the keeper of the Saltwharf Counting House. While wearing them, you can perform rapid mental arithmetic flawlessly and can determine the exact contents of any container of coins or gems you can see within 30 feet (count, denomination, and total value) with one minute of study. Once per day, you may cast the Identify spell without components. The spectacles bear a faint transmutation aura, and their lenses are etched with the same cipher glyphs found on the ledger pages — a detail that may matter to a careful scholar.
