I'm seriously. posted:
I went to an antique shop and got an old pepsi bottle that looks like it could've been made anywhere from the 60's to the 80's. On the bottom there are the numbers "188" 79" and "18" Could any of those mean a year? How can I tell what year it came from?
check on ebay and see if there are any like it. also, you can google it and see. good luck
um… it may be the 79 number because that would be the only reasonable and logical answer
cut in half and count the rings.
Most likely 79 is the year. You should have asked before you buy.
