My monogram mini pochette has a date code of SD1057. I know SD means made in the US, but I read somewhere that the first and third number should represent the month, and the second and fourth number should represent the year that the bag was made. This means that this bag was made in 15/07? It doesn't make sense. I bought the bag in a boutique, so I'm pretty sure it's authentic, but I'm just concerned with the numbers. Do any of guys have similar date codes? Thanks everyone for your help.
