Yeah. I worked for Bell Labs during the breakup, and had a few shares of AT&T from the ESOP. For years afterwards I was getting tiny little checks for offers to sell my piddling positions in Agere, Lucent, Avaya, etc.
Caution - AT&T is an extreme case, but for any company going back to 1945, you are likely to find spinoffs that have to be taken into account / sold as separate positions, etc.
Another thing to consider - companies sometimes qualify portions of their dividends or special distributions as “return of capital” (“untaxed distribution”). It’s not a frequent occurrence for common stock in most companies, but it is possible (it’s a fact of life for some other investment classes). If such a thing DID happen, the rule is that the distribution was not taxed, and your cost basis is to be reduced by a corresponding amount - your basis is no longer what you paid for it, or what it was worth when you inherited.
