It's not an overbet, but I think it's just larger than necessary. If you'd bet 90c-$1 you'd risk a bit less and have the same effect. (But this particular guy isn't folding btw)

You also can valuebet the same amount and set up a nice turn shove, this way you wouldn't have bet sizing tells. I know most low stakes players don't pay enough attention to know this, but forcing yourself to think more may help you pick up on others tendencies.

As for who to do this against, it depends on your reads. I have met players who minbet as a signal they are weak and ready to fold, and others minbet because they have a little something and aren't easily willing to fold.

Getting it in pre isn't very good with 44, you're barely ahead of junk hands like J5o, better to hit a set and get your value postflop.
