Occasionally when someone comes over, they will open my door with a dollar coin. This is a pain, and sometimes I am working on something private when they open the door. I would like to be able to make it unopenable with a coin without unscrewing anything. One of my ideas is to wedge something in the lock, but then I might not be able to unlock it.

    you need to provide pictures of the door lock.

    From the description, you are inside the room when they come in? Wedging the door will be easier than wedging the lock. Commented Mar 24, 2021 at 9:54

    Have you tried asking them to respect your privacy? Commented Mar 24, 2021 at 11:12

    How many people just happen to have a dollar coin in their pocket? This sounds premeditated.

At its simplest, a door hook on the inside of your door will do the job for about $2. at a hardware store. You twist the hook into one side of the door and the loop on the door frame (or vise-versa).
No tools needed.

… A simple request on the outside of your door.

Good luck.
