There are a number of different guides that help with this, but there are definite variations that can make this difficult.
Morgan dollars, for example, have different criteria for the different mints. Since by the 70-point system, uncirculated is shown in MS (Mint State) grades this makes sense. Most of the coins that came out of the San Francisco mint (though not all) have sharp strikes. Most of the coins that came out of the New Orleans mint have softer strikes. Therefore, an MS65 San Francisco could look entirely different from an MS65 New Orleans coin.
There are many series with these types of differences. It can also vary by date and die marriage. There is a Bust half variety with some unstruck letters that came that way from the mint.
Lots and lots of factors to consider!
