When you try to open a chest in your My Items -> Chest page, you are given the option of purchasing a silver key for a 50c deduction from your coins.
Was this intentional? or a glitch that hasn't been fixed?

Update:
YES IT WORKS for those that are asking.
50c gets deducted from your coin total and the chest you clicked opens displaying the contents.
