Those are 1999/2001 Cobra wheels. They returned as an option on 03 and/or 04 GT's, as Ford was clearing some overstock from the shelves before the production rollout of the "new" S197 platform. Never seen an aftermarket reproduction of them, so they are likely legit oem.
As far as value, look up a set on Ebay and use that as a barometer.

All the usual bolt-on's /200 I6, C4
