I started collecting Coca Cola bottles recently and i came across this at an antique store. $75 is quite high to just buy it without advice.... I can always make an offer as well. Anyways i am trying to gather information about this bottle beforehand. From what I know it is a 1915 Pat date Coke bottle from Fresno, California. The triangle marking is for Illinois-Pacific Glass Corp. That things I don't know is the year it was made exactly? Does the marking "7-6" mean 1926? What does the mark 7 on the lip mean? I looked the bottle over and it looks quite nice with no obvious chipping or cracks. Thanks for any info!
