khj- True, Type IV can be either originals, remainders or reprints.
(I edited my earlier post to make it clear I was referring to Type IV originals.)
But, by far, they tend to be reprints.
Type IV: 1880-82 ,-Perf 11 3/4- 2p, 9p (2p never placed in use). Speck or dot of color on curved line below center of "M". The Type IV originals, compared to the Type IV reprints, are distinguished by color for the 2p, and "rough perf 12" for the 9p.
For the purposes of this discussion, I am assuming that a "dot" seen below the center of the "M" in Express stamps indicates "Reprint"- because that is a likely assumption. But, if you believe you might have an original Type IV 2p or 9p, then seek expert opinion. (There were also Type IV "remainders" (perf 11 3/4) from 1881 that were purchased by a stamp dealer after the discontinuation of the Samoa Express service, and distributed to the market. The colors are somewhat different between "remainders" and "reprints" See Samoa Express Forgeries website

Reprints are also Type IV! Reprints are often perforated on all sides ("uncommon" to "doesn't occur" for the originals).
Reprints tend to have whiter paper, and the perforations are 11 3/4 and 12 1/4.
The reprints were made by the original Sydney printers, but the sheet size was larger (40: 8X5). An estimated 50,000 sets (1884) and 100,000 sets (1892) were produced. Reprints far outnumber originals.
