To my eyes, it's the pickup covers that look the worst for wear over time, compared to the other hardware items.
There is an alternative to using gold plated pickup covers. It requires some DIY skills and patience though.
That being, plastic pickup covers with gold foil adhesive tape that has been custom cut and applied.
Two benefits: lack of metal in the cover, so the pickups' high frequencies won't be affected, and lower cost to replace after years of wear - in this case, you re-use the same plastic covers and just re-do the gold foil sticker tape.
