I have a bag from 2000 and the creed says 2K for the year. I don't know if they did this on all of their 2000 bags or just some. I bought it from the full price store.
My Tribeca says M if the letters state the month then it would only go to L as L would be the 12th month. So I think it is the letter for the Month it was made in. M= May or March?
It stands for January 2009. Coach does do the letters to represent each month starting with A and ending with M. They do not use I for some reason. I have no clue why they do it. So
A= January
B=February
C=March
D=April
E= May
F=June
G=July
H=August
J=September
K=October
L=November
M=December.
Then of course the number stands for the year. So 01=2001 and so on.
