However, the A to the right of the 7 tells me that this piece of glass has a high probability of either once being a Coca-Cola bottle or a Pepsi-Cola bottle.If that is the case, this piece of glass may be our exception to the rule and the 7 to the right of the symbol may not be a year code at all.In 1941, the United States of America formally entered World War II on both the Pacific and European fronts.Resources became limited as many industries focused on manufacturing supplies to support the war effort.As a conservation measure during the war, the amount of glass used for many bottle types was reduced. The number in that picture could either be a 6 for the plant code, meaning it was made in Charleston, West Virginia, a plant that was in operation from 1930 - 1963 (Society for Historical Archaeology) or it could be a year code of 9. They axed the diamond, and instead were left with a simple I inside of an O (see pictures to the right and below).You can't really tell from the picture, but the green glass in Exhibit C is quite thick, thicker than anything we would see today, which leads me to believe that the glass was indeed manufactured in 1939, and has been sitting in the creek ever since, waiting for me to find it. If it is a year code, the thickness of the glass and the lack of a period after the 9 suggests a manufacturing date of 1939. The general trend, however, remained the same with the plant code on the left of the symbol, and a date code to the right.
Since 2063 has yet to pass, and the company did not exist in 1863 nor did it use that symbol prior to the 1950's, the only possible year of production is 1963. I am unsure of whether or not this particular example follows the general trend of date code to the right of the symbol. If we assume that the 7 is indicative of a year, it could mean anything from 1957 to 2007.(I am also a giant nerd and find this stuff fascinating.) I will never know exactly what year the previous glass was manufactured, but while digging I discovered that I owned pieces, that with a lot of persistence, could be dated to a specific year.But first a little about the The history is a little confusing, and as is usual of the internet, varies from website to website, with each website having their own sources, and their own account of what happened.The symbols, therefore, are quite faded.) Production of this particular mark ended somewhere in the mid 1950’s.There is no exact year in which production of the symbol stopped, as various plants ended use of the mark at different years.
