The Moon most likely had a unlocked rotation. See this [Wikipedia page](https://en.m.wikipedia.org/wiki/Tidal_locking) and maybe my recent answer to [this Worldbuilding question](https://worldbuilding.stackexchange.com/a/169281/62241) for attempting to solve for a tidal locking timescale.

[The Moon became tidally “locked” within 100 million years](https://www.forbes.com/sites/quora/2018/07/11/what-did-the-moon-look-like-from-earth-4-billion-years-ago/#1b6480811151) of it's formation. I guess this would be based on a calculation like that of @BMFForMonica .

Do we know if the moon had an initial rotation or did it coalesce tidally locked. If it had an initial rotation how long would it take to become tidally locked?
