Old Case Gin Bottle with Crosses on Bottom - Help Identify

I need help to identify this bottle. Believe it to be a case gin bottle. Can anyone identify when it is from and what is the significance of the crosses on the bottom. It is darker green color when held up to the light.
Thanks

Nice bottle! I'd guess, based on the squared shoulders, it dates to the late 1700s. The color suggests Low Country manufacture. The cross-marks are probably not significant -- they may be centering guides for applying the pontil rod, for example.

Thanks Harry. What I found to be interesting is that the crosses are all raised. not depressed into the glass
