Set Date(s)
12 October 1899
The first stamps produced especially for the German colony in Karolinen were overprinted versions of German Krone / Adler issues.
This series was first available for use on 12 October 1899.
In May 1900, a second set of overprints was introduced bearing the same “Karolinen” overprint, but at a steeper angle (56°). The 48° Overprints are much rarer, and are valued as such.
The 3 Pf and 25 Pf can be found with plate flaws on the underlying stamps.

Posn. 33, 38, 83, 88

Posn. 22, 27, 72, 77

Posn. Unknown
These stamps were printed in 10×10 sheets, with two sheets per printing pane, arranged vertically. As a result, gutter pairs (in German, Zwischtenstegpaare) exist containing stamps from the bottom row of the top sheet and the top row of the bottom sheet.
