I don't know if this has been mentioned on the forum yet, but H is doing away with the lettered date stamps! I was in the Mad Ave store today to take a bag and some accessories to be cleaned. While I was there speaking to Claude, I mentioned something about the date stamp on my birkin. He in turn said to me that they are completely doing away with the letter date stamps and changing it to something else completely different, and NO ONE knows what it will be! He said that this is, of course, to make it harder for people to counterfeit the bags! Wow! Anyone else heard about this or have more info? Sorry if this is a repeat thread. I did a search and didn't see anything.
