Guidelines for adding mixed fraction denominations? [solved]

tl;dr: I think the guidelines for face value in word form should specify 1) using a hyphen for mixed fractions, and 2) use the fraction from the coin, not "3/2" when the coin says "1 1/2".

I think there should be explicit guidelines for entering mixed fractions (items like "one and a half") into the "Face value in word form" field.

Looking at 1 1/2 Pfennig in particular, I find ten when I search for a "Face Value" of "1-1/2 Pfennig". one when I search for "3/2 Pfennig".

Searching for a face value of "1 1/2 Pfennig" has 56 results. Most don't have a face value of "1 1/2 Pfennig", but the results do include coins with that denomination not found when I search for "1-1/2 Pfennig".

I think the guidelines for face value in word form should specify 1) using a hyphen for mixed fractions, and 2) use the fraction from the coin, not "3/2" when the coin says "1 1/2".

Is there a better place to discuss guidelines? The "Numista coin catalog" forum seems like the right place, but guidelines aren't one of the listed aims for new topics.

I agree that would indeed be good.
Im often not sure if I should write is as 1-1/2 or as 1 1/2
I guess some have also been written as 1.5

The same goes for other denominations such as 2-1/2 etc.

3/2 I removed that one, not sure who put that in but must have been before my time as a referee.

This is no longer relevant with the use of Unicode fractions.
