Why not just use asciimode?
To understand why \footnote{\type{...}}} doesn't work, you need to
understand TeX's "digestive system". \type{...} (and asciimode) work by
modifying the catcode tables. However, they are are used inside a
footnote, the argument of \footnote is parsed according to the catcode
table which is active when footnote is passed. Under the default catcode
table, % is a comment, so when you type:
\footnote{\type{*\$%
}}
the argument of \footnote is `\type{*\$}`
So, if you want \footnote to "see" the %, you need to activate a catcode
table where % is a letter. So, the simplest solution is to use \asciimode.
