It's the purple vouchers some troops carry and is used automatically, 1 per investment, during invests of gold during the investment faction quest. I like to use mine then sell the remainder right after the fq then collect them as time goes and I have enough during investment quest again - if you can use that strategy depends how fast your generals die though.
