Let me show here some varieties I found in my collection for Solomon Islands coinage before the recent and new 2012 coin family.
Starting with the
10 cents, we can see that the
2010 (
does a 2008 exist also?) type has a different typography than 2005 (
KM#27a):

Exactly the same happens with the
20 cents 2008 and 2010. Both have a different typography than 2005 (
KM#28):

For the
50 cents, we can see also the different typography in
2008 (
I wonder if there is also a 2010 issue). Besides, this denomination has now a
magnetic core, it's not CuNi like 2005 (
KM#29):

And finally, the
1 dollar coin, once again we find the different typography in
2008 (
is there a 2010 issue?). And it too has a
magnetic core, so not CuNi like 2005 (
KM#72):

Any confirmation about the smallest denominations (1, 2 and 5 cents) for years after 2005 and before 2012 would be great! (my latest Krause just lists
1 cent 2010 and
2 cents 2006)
Updates from Antoine Clerc:
1 cent 2010 also has the narrow lettering of the other 2008 and 2010 denominations.
2 cents 2006 has two interesting mint marks (meaning?). See them both in
Antoine's PDF.
