Right now there are no way to escape $ in arguments which support 
variables.  This is a bug.

Possible workaround is to use some variable defined with module 
which doesn't support variables, e.g. you may do so with geo:

    geo $dollar {
        default  "$";
    } 

    ...
    set $var "${dollar}uri=200k"
    ...
