The pounds are not all that great, but still probably work more on
ebay than what you'd get if you banked them ($2 each).
The $1 and $2 are typical "last year of issue" notes, the types circulating in 1984 and 1988 respectively, that were kept by many folks as the announcement to replace them with coins came through. Again, no more than double face.
I'm not familiar enough with the NZ notes to date them without looking it up; I think the $2 and the $1 with the same signature are from the mid-1980s.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
