Many people like the green patina, or verdigris, that copper takes on over time due to oxidation, but didn’t we give her a face lift back in ‘86? I think the plan is to give her a good refurbishing every 100 years for her birthday. The total cost in 1986 was in the ballpark of $250 million, according to the GAO. Today that would be about $550 million. There is no telling what 550 million 2016 dollars will be worth on her next birthday in 2087, assuming the expenses in 1986 stay the same—which of course they won’t. She will be one hundred years older and probably require more structural replacement.
