Bottle bottom numbers

[winterwood52]

I have an amber bottle with the following alpha numeric numbers embossed: clockwise they are top C6, right 87, bottom, c86 and left 31. No other identification/trademark/makers mark/, etc. Anyone?

What kind of bottle? A clear picture would be a big help.

Of course. See attached.

It's a modern beer bottle. Maybe from 1987. Not much more to tell you beyond that.

Thanks for the info. I'm new at this and more interested in history than value. That said, how did you arrive at the approximate date?

It could be 1987 because of the C87 on the right. You can tell its modern because of the braile on the heal and the screw, and ridges on the bottom

Makes sense. The other numbers must be glass manufacturer numbers then I suppose and mold numbers. Thanx again.
