Reference to the same denomination the KM# before or after?

Quite often I would like to be able to find the km# before and after the km# I'm just working on:

Example: let's say the 1/2 dollar before or after the km#142 in straight chronology; which would be
before km#116 and
after km#199

I'm sure it's nearly impossible to built this in automatically, so maybe we can use "References" for that?

I have set up a CR for the US, 1/2 dollar, km142, to see what will come out of that.

To get a consistent system it would mean a lot of hard work and thousands of CR to be created and approved......

It would be useful if each link had a short text field explaining why the link is related. Previous, Next, Mule of, Same series, Same design, ...

Absolutely. Previous is better than before and next better than after
thanks for the suggestion.

Just have a tab open with a search that sorts for reference for a certain denomination. That's how I would do it if I work on overspanning issues.

Thanks for the suggestion. That system I've used as well. It's probably the easiest way to tackle the problem.
