What do you mean you’ve heard “could of”? Of course you would have heard that. That’s literally how it’s pronounced. It’s just not spelled out that way, as the above person noted. People end up erroneously writing it like that because that’s how you say it out loud.
Do you pronounce “could’ve” in a way that doesn’t sound like “could of”??? Curious to know what that would sound like.
I have definitely heard “could /should of” by native speakers more than once.
