Nothing of value, but there usually is some (silly, IMO) justification, such as badges and warranty (practically useless). Funnily, Comodo starts its list of key features with "value" [0]. They also seem more expensive now than I remember them to be (hundreds of USD per certificate/year), and still call both X.509 and TLS "SSL".

Sometimes I hear about people just looking for "SSL certificates" because somebody told them that they should have one, and search engines would lead them to those websites; probably that's how it still works.
