I have been away from the forum for a while and missed this entire thread, which I read in one go.
@SupaUltra_J, I am so very sorry about this situation -- you seem to be handling it better than most of us would.
I know this is not helpful, but it seems to me that there are several scenarios:
- OP is not being truthful and swapped out the bag at some point.
- The bag was the same throughout the whole saga, but:
- Both an experienced reseller and an authenticator, both of whom I would trust personally, are wrong.
- Or Hermes is wrong.
I would personally go with Hermes being wrong. This is a rare bag and it is more likely that someone at Hermes is not familiar with it than that someone made a fake of this model and fooled two people who know their bags (or that OP had the same exact fake of a fairly rare bag sitting around to execute a fraud).
Personally, I would use the bag and believe it to be authentic in this type of situation, but it looks like the most unfortunate consequence here is that OP would not be getting her bag back (since I believe Hermes destroys those items they deem fake). My heart goes out to the OP and all parties involved here. I can't even begin to think of who is at fault here.
As a separate discussion, I see microchips being brought up as an authentication feature. I have no idea if Hermes actually uses them, but I would be fascinated to learn more if that's the case. However, the odds of Hermes having the right technology in 2005 are minimal and I highly doubt that that is what Hermes used to issue an authenticity verdict. (As an aside, I may be wrong, but because of European data privacy laws, I believe Hermes would be required to tell customers if they did indeed use such technology).
