Levi's 511 Red Tag Classic Black Jeans Size 33x32 cant decipher the codes, so here's what we figured out back of top button has code 3411 that's a factory code it seems that the date is usually near the factory code . and that # is 430 also pocket has the Big Levi logo stamped on it, see pics ..it says "for over 135 years", which would be 2008... dont know how long they had the #135yrs stamps running so the 430 "could" mean 43rd week of 2010 pre-owned condition is Levi's Perfect see all pics for condition
