Is standard oil NJ stock worth anything?

Standard Oil of New Jersey, which was formerly a major oil company, ceased to exist as an independent entity when it was broken up in 1911 due to antitrust laws. Its assets were redistributed into several companies, including Exxon and Mobil, which eventually merged to form ExxonMobil. Therefore, Standard Oil NJ stock itself no longer has value, but its legacy continues through these successor companies, which are publicly traded and have significant market value.
