going through all my buns to sort them out, had little problems so far, that is until i came to my reverse D's 2 of which are obverse 4 which is easy to identify one is very worn but looks like 6+D however i am stumped on one more, which is either 2 or 3.. as these coins are worn, how do i distinguish with such minute changes. same with 1889 obverses. and my second question, what are the raritys of all the pairings
