I don’t think it’s fake (at least I’m not seeing any red flags), but it’s in rough shape cosmetically—not just the scratches, but the crown guards appear to have been polished rather sadistically. Maybe fine for a daily beater if you can get it for a price that reflects its condition (like no more than $1,000 USD in my estimation, and preferably less). Just bear in mind, these aren’t rare: you can toss an $1800 dart in any direction and hit several that will look far better.
I guess let’s see if anyone else has authenticity concerns. I say just don’t overpay.
