I also came across this issue and after inspecting the source code I couldn't find why it didn't work. I then started looking for a work-around and found that this works:

Place the following in the http block of your nginx config:

    geo $dollar {
        default "$";
    }

Then, you can use ${dollar} in your replace_filter rules to get a single $.
