I don’t think that was the OP’s original thought in terms of resale.Hello, I would like to know why it is so important for you, as for others, to know if it will become a classic piece or its resale value. Unless it is bought for that purpose, I think we should buy what we like and it doesn't matter if it's classic or not, it's something that we will take for ourselves.
The Love and JUC launched in 1969 and 1971 (though the JUC was relaunched in 2000s) but that is a nearly 50 year history with the house.
Bvlgari’s B Zero 1 collection launched in 2000 & we all know how much history the VCA Alhambra is engrained in its history.
My mom has Tiffany silver and gold pieces from various collections that have been now discontinued. If you Google “Tiffany discontinued collection purseforum” there are plenty of great designs that have come and gone (some have come back even).
I think Tiffany’s greatest advantage to Cartier & VCA & Bvlgari is their diamond work though with their new collections, I would be surprised to see it still in the house in 15-20 years.
That being, IMO, I think the new collection is beautiful though nothing is exactly groundbreaking.
