Divalent silver (Ag2+) is a homologue of its well-known copper sibling, and it comes with Jahn-Teller effect, paramagnetism, and strong influence of electronic correlation on chemical bonding. I will briefly outline our two-decade lasting efforts to show that many analogies exist between parent compounds of oxocuprate superconductors and fluorides of Ag2+. Strong magnetic superexchange and prospect for achieving superconductivity in the latter will be discussed.
