Stock Watch: How do I figure out if the IV for a put option is high or low?

I'm interested in selling a put for $MU at a strike price of around 53. The IV for Aug 3 is .52365.

I'm bullish on this company and I think 53 with a $1/ share premium is a fair price.

I'd post this on r/options but apparently they don't want any questions on that sub. If there's a better sub to ask, let me know.
