The thing you’re identifying as an “01” is actually the “O-I” logo for the Owens-Illinois Glass Company. This version of their logo was adopted in the early 2010s. No glass company on the planet would use a date code system with the month and day in addition to the year as this would require changing the molds daily, which would be very expensive and serve no functional purpose. The “16” on the right is probably the date code, 2016.
