The most common version number for a brand new module is 0.0.1.
Most new modules are not release quality but just alpha or beta quality. Releasing a new module with a 1.xx version number is a bad idea, even if it has been extensively tested in-house, because it can have problems with its API that would remain undiscovered until somebody starts using it for something the developer never though.
In my opinion it is a better idea to use a 0.xx version number that says, try it, tell me what you think, and then I would try to correct the problems to finally release something stable.
