: I have read that the numbers on the base of a glass are supposed to have a code that lets you know when the glass was made: the first digit is the time of year (by quarter) and the second is supposed to be the month of that quarter.
: I have a problem with this definition, because it does not explain single-digit numbers, nor does it explain when the first digit is larger than 4 or when the second digit is larger than 3.
: I think that the numbers are a quality control measure for telling which mold the glass came from -- if there are a consistent number of "flawed" glasses with the same number, they know which mold to look at, wheras if there were no numbers, they would have to inspect every mold.
: If your glasses are just plain glass, with no added design, they are worth about $1.00 or less.
