They range in value from $1 to $100k+ depending on the particular series (mostly identified by the watermark) and, most importantly, the grade. I've got a near complete set except for all of the 2 issues.
I had better go take a look in the old stamp albums. Haven't looked in them since I was a mad stamp collector as a kid. I remember having loads of kangas.
I have a black and yellow kangaroo - exactly the same show on the first post. How can I work out how much its worth?
Find out the watermark, establish a condition, look up the book value and divide by about 3. Just guessing on the divide bit, but the book values are almost always overstated full retail prices.
