What's your MOST valuable bag ever?

My most valuable bag is a Dior Saddle bag my husband bought me for our first Christmas together. It's not the most expensive bag in my collection, that would definitely be a LV bag.
 
It used to be my Manhattan GM (but then I gave it to my mom).

So now it would probably be my Batignolles Horizontal....I did just buy a Keepall 50 but bought it used so I paid less than I did for my BH (because I bought the BH new at the LV store).
 
not the most expensive but my most valauable would be my MC trouville. A gift from my mom, bt she asked me to wait until we get to europe and she'd buy me one. In short, the bag and a trip to europe were her gifts for my last birthday. It was really a memorable one. She's the sweetest.
