When searching for something you've lost, try to remember the last place where you know you had the item, and carefully re-trace your steps and movements from there. Pay careful attention to nearby areas where the item may have bounced, rolled, or blown that may be out of direct sight. If you don't find it, put up LOST posters in the general area, including a picture and offering a reward if possible. You can also use online bulletin boards that have a lost-and-found section, and don't forget to check with the police, in case some good neighbor already found and turned it in. Good luck!
