I was halfway through a box of halves without finding anything and then the 1974-D DDO coins started showing up! I found 3 in all, this picture is of the best one. No silvers, but I did find a 1981-S Cameo Proof Type 2 (flat S mint mark), and a couple of other NIFCs. Just "like a box of chocolates"!
I am curious if it is difficult to find the 1974-D DDO in circulation and am I likely to not find another while CRH? I'll probably continue to search of course, but might need a more experienced voice in order to manage my expectations. Thanks.
