Louis Vuitton Sarah wallet

I have owned this wallet for about 15 years. It comes with the box and dust bag but I do not have the receipt to verify authenticity. It is in very good condition, with minimal wear on the corners. When not in use, it has always been stored in the cover and box. I use LV exclusively and date codes are extremely difficult to find, I cannot even find on the new bag and wallet I got for Christmas. It is authentic, just cannot verify, the LV store won’t verify either.
