A $10,000 treasure hunt launched across Philadelphia on Oct. 13, running through Oct. 17. The event, organized by the coin dealer Stack’s Bowers, hides certificates that participants can redeem for rare coins and special bills.

The five‑day hunt is open to both city residents and visitors, offering multiple chances to locate the hidden certificates during the five‑day period.

This is the second year the organizer has run the citywide search, aiming to give the public an opportunity to claim the advertised prizes.
