I think Numista has it wrong, can happen, we have seen it before? When Numista copied the data from KM, where that type is shown as follows

I suppose the guy copied the 3 year lines wrongly as
1952B Small date
1965
1965 Large date
So the overdate 1965/3 is missing in Numista and thus the small date from 1965 doesn't exist! All dates of the 1965 are large compared to the 1952B.
The year lines should be
1952 B
1965/3
1965
There is no need to talk about the dates
small date 1952

Large date 1965

So you can make a Change Request to have the year lines put as they should have been from the beginning.
