Found this on the coast. Haven't found one like this before. The seem stops at the lip. Theres a weird almost pontil looking hole at the bottom. What appears to be an L on the bottom. Faintly can see "COKE" on it. Any help would be appreciated. Thank you
That 'hole' was there to accept a metal pin which held it in the right place while the applied color label was put on the bottle, without it labels would get all screwed up...
