Given the M and W I don't think "mathematically possible" is the criteria here.

Here's some options that fit in 4 pixels: https://i.imgur.com/LtQ6eb7.png

Some of these can look like $ if they're really tiny, but generally you'll need a while to figure out what's they're supposed to mean if you don't know what you're looking for.

Top right is the winner for me

Nice. Third from the left on top is great -- pretty unambiguous, and consistent with the w's and m's.

This. It’s what the C64 (and I guess many/most early home computers) did. No need to draw the whole vertical line if it doesn’t reasonably fit.

…and now I realized that even the ubiquitous IBM VGA 8x16 font does this! Single-pixel-wide counters would just look really bad, and even more bad on CRT monitors.

So which is it?

I assume that "proper $" means the middle line is fully drawn, forming the two closed spaces at the upper left and lower right.

Can be pulled off with enough context https://i.imgur.com/pXA69Xw.png
