There were a LOT of comments that he could have made as he spotted the gold ball, but not having any one to hear them made using them a waste. So instead he simply picked it up, and shoved it into the backpack, one of the minor side holding pockets. The main pocket was full, and the secondary was as well, so he had use the minor pockets meant for holding small amounts of things, like ball bearings or slugs for the revolver. He did, however, make sure the pocket in question was empty, no sense finding out it reacted poorly to something by it exploding the pack off his back. He planned to examine the thing later, as right now he had to get out before Aurelia murdered him for giving her a heart attack.
