Authenticating after receiving item

[devs_flfinds]

I purchased a designer wallet and the listing didn’t offer the authentic guarantee, but I just assumed it was because of the lower price point compared to a handbag. The seller says it’s authentic, but I cannot find a date code in the wallet after receiving it. Is there a way to request authentication after purchasing?

Please post pictures (or the item number) of the item.

Item number is 205237211739

Wallet matches photos, there’s just no date code, serial number, etc. I messaged the seller and they confirmed it is authentic but couldn’t provide any more information.

I don't see obvious problems but I'm not a Burb expert. 

I'll tag @mupcycledcouture  and she might be able to offer her opinion.
