What's so Valuable Behind those Doors?

​There are many beautiful doors in Idaho’s statehouse. Most are wooden, many with glass or frosted glass windows in the upper half. Two, though, are unique. To enter certain offices in the Idaho Capitol, you step through the openings of door-sized safes. The gleaming steel doors with hefty metal latches, knurled knobs, and gold-leaf lettering once protected the state’s treasury back when physical money from tax revenues was kept there before finding its way to the bank.
 
There is little need for enormous vaults to protect cash anymore, but when the renovated statehouse was reopened to the public in 2010 we found that those historical doors—minor treasures in themselves—had been retained.
