“So where was that Australian Coke Can, canned/bottled/produced?”

If you were going to do a “taste test”, this would be fairly important to know.

Was that Coke Cola can purchased from a South Australian Petrol Station REALLY canned in Adelaide, or was it imported from another state?

So I did a search around the internet, and found mmmmmcoke’s collecting guide on eBay.  For the current series of Coke Cola can, if you look on the bottom, you’ve see information like this:

The general stamp format is as follows:

So for the two cans pictured above:

S = Sydney, (or they also use X for Sydney)
M = Melbourne, Victoria
L = Launceston, Tasmania
A = Adelaide, South Australia
