It might be reasonable to have your wife pick half a dozen or so favorites, then sell the rest. Especially if you're trying to pare down, build a nest egg, etc. I bet there's a market for them (TBH, I haven't looked).
On a sort-of similar note, when my MIL died in 2017, DH inherited thousands of shares of a particular stock. His dad worked for the company for decades, so the shares have sentimental value to DH, beyond their face value. The problem we have is, the company is doing okay, but not great, we'd be better off diversifying (more), and selling at least some of the shares. In fact, if DH's parents came back from the dead, they'd (figuratively) smack him upside the head for being sentimental about an investment. I asked DH the question--how many shares do you need to feel sentimental about? Does it have to be 10,000? Could it be 1,000? 100? We aren't hurting for cash, but using that money to, say, pay for college for our kids would be very much in keeping with his parents' philosophy and life goals.
