New description:
{{{
sage: x.coefficient?
...this works...
sage: (x+1).coefficient?
Object `coefficient` not found.
sage: (x+1).n?

Comment:
Actually there is still the issue why you don't get the help with `?`:
{{{
sage: x.coefficient?
sage: (x+1).coefficient?
Object `coefficient` not found.
sage: (x+1).n?
...this works...
}}}
