Thanks everyone for the opinions!!! I actually went and bought the purse then got it authenticated by memes treasures and sure enough it's authentic!! The purse has no patina and is lighter than the artsy that I bought last March (and used minimally). [emoji7] I'm a happy mama.
The patina difference is huge between these two bags though. I wouldn't pay the same price for both bags.
In any case, OP: this thread is a good example that value is hard to determine. You have to make the decision for yourself.
I had to post again because I don't think people are giving you good advice! Here is a seller in your same state selling the bag for $850. Plus you can't get it authenticated on TPF unless you have a link to an auction. While it is an LE bag, the demand is low in the resale market. Now if this was a roses speedy, I'd say go for it.
