I'm trying to work out what a set of Solomon Islands circulating coins constitutes. I've seen/have examples of most of what is listed in catalogues but there a few whose existence I'm not sure about. Has anyone got or seen any of the following:
1c
1989
2c
1989
5c
1980 (no FM mintmark)
1987
1989
20c
1978 (no FM mintmark)
1987
Note that 1980 5c pieces and 1978 20c pieces both exist with FM mintmark and are reasonably common, but there are supposedly non-mintmarked versions which I'm looking for.
