I'm a devout practicioner of MPT, EMT, AA, use low-cost MFs kind of guy, so I'm in unfamiliar territory here...
DW used to work for a company, and has 19 shares of stock. (This is low-tech; it's a paper certificate!) When she left company, the shares were a couple of dollars apiece, not worth selling. Fast-forward to today. Company is now trading in the low $40s.
I have an account with Vanguard, but it's all MFs, no individual stocks. As far as I know, I have no brokerage account there. Assuming DW wants to sell this stock, what's the lowest-price way for me to go about it?
