The last four times I've used a silver gauntlet on an arcane coffer (with two separate characters and in all three lairs) I've received a single white pearl.
At first I thought I was just unlucky, but since the lowest possible reward (according to tooltip) is 2 white pearls, only receiving one, four times in a row, is clearly some sort of bug (I hope).

i did think it was strange that i only got the one peal, insead of the two that it mentioned
I only actually used the gauntlets twice though, so...
Give a man a fire and he's warm for the day. But set fire to him and he's warm for the rest of his life.
