O.101, R1. This overdate, often called the punctuated date is from one of two die marriages (O.102 is the other). Look closely and you can see much of the 0 under the 3rd 1. There is a bold die dot between 8 and 1. And depending on who you believe the fragment between the two 1's is either from another nick in the die or it is what is left over from the earlier 1. In general the strike is just fine on these overdates but the relief is usually not as good as the yeardates due to lapping. Stars are always weak on the left obverse of the O.101 and, oddly, just the opposite on the O.102., same die. How can that be? Only a remarriage explains it (but you have to wonder why remarriages ever happen).
