High-end Consignment Stores on West 29 and 30th Street
High-end consignment stores on West 29 and 30th Street between 7th and 8th avenues might be interested in your fur coats.
They can pay better if the coat is from a known brand, but you should be prepared for the fact that fur resale value has dropped a lot, so don't expect to get anything close to what was paid originally.
