A centuries-old newspaper, found in a Goodwill store in New Jersey, has been appraised at $18,000. The artifact, a copy of the December 28, 1774, Pennsylvania Journal and Weekly Advertiser, features the ‘Unite or Die’ snake logo and signatures from John Hancock. It was acquired by The American Philosophical Society in Philadelphia. The donation highlights the value of thrift store finds, as another shopper once bought light fixtures for $7 and sold them for $2,600 on eBay.
