First:
5 cen coin.
2000 year piece has 2 subtypes:
thin inscription
thick inscription.
Question: Which type of inscription have all other years? or what do we mean under " inscription" ? the word " SWAZILAND" , the word " CENTS" , year, or all of them? Please add more details to help people.

So if all other years have another inscription ( let call it NORMAL INSCRIPITON ) , and 2000 type has thin and thick inscription in comparing to so-called NORMAL one, - we must put also comment " normal ( or common) inscription" near all other years.
And, if one of that inscriptions are common one, as in other years, we must comment just on another type - " thick inscription" or " thin inscription"
Another way - please put photos of both inscriptions in comments.
Second:
2 Emalangeni coin. Also, I think there are some incorrect comments.
If large date is 7,3 mm (1996), 2010 type also could 7,3, because there is a comment " large date" . And, I see as well a term " wide date 5,3 mm" which is also incorrect I guess..

THird:
20 cents coin. KM 50.1 ( large bust) and KM 50.2 - also large bust.
