Try shopping for bargains at Goodwill stores. Fifty-eight cents could turn into more than $20,000. A couple who sell vintage clothing stopped at a North Carolina store and bought a sweater they liked at a price they liked—58 cents. They wanted it to sell at their vintage clothing store. Months later, they saw a TV documentary on Vince Lombardi and realized they had his West Point sweater. They found a nametag in the sweater, did some research, and contacted Heritage Auctions, who authenticated the sweater using the latest equipment. It was auctioned on February 21, 2015, and brought $43,020, well over its expected $20,000 price.
