I note that most currency symbols are upright by default: $\textyen\ \textdollar$

The MathJax TeX fonts used in v3 do not have an upright version of the pound symbol, only an italic one, so that is why the italic form is used (That comes from how TeX originally handled this symbol).
The version 4 fonts have greater glyph coverage, and include an upright version of this character, which is what \textsterling will produce in v4.
(That comes from how TeX originally handled this symbol).
Yes, the pound symbol is in the italic $ slot in Plain TeX.
