I've been retired for several years and have been collecting social security during this time. Would there be any value for me to get your social security books and materials at this late date or have I missed my opportunity?
It depends on your age. If you are under age 70, then you could suspend receipt of your retirement benefit and earn delayed retirement credits until age 70. They would increase your benefit by 2/3% per month for every month of suspension. If you're over age 70, then it's too late to do anything to increase your benefit.
