The third stamp in this series is the 25 Mon. This orange stamp was never issued and therefore any stamp claiming to be used has a fake cancellation. The stamp is designated Scott #3 and Minkus #N3. Black and white images are from Brady-Tyler and colour images are from MikeG Canada (Stampboards) and other sources.
These high value stamps were just paper labels when they reached Inchon by 1885.4.5. To reimburse the printing costs, the Korean Government sold the unissued stamps by 2 February 1886 to E. Meyer & Co. (Sechang Yanghaeng) of Chemulpo, which in turn sold them to the stamp trade.
The Catalog Value as shown by Stampworld is 12 Euro for Mint. No Watermark and perforated 8½ to 10:
Please, this is misleading. The 25,50,100 Mun stamps were never issued. These higher value sheets reached Korea only by April 5, 1885, when there was no postal service anymore.
So “25 Mon issued in 1884” must read “25 Mon, unissued”.
Same with 50, 100 mun.
“This orange stamp was never issued for postal usage ” is again misleading. It suggests it was eventually issued for non-postal usage. But that is wrong. It was never issued* period*. Any “usage” or any “marking” is purely private folly or fake. So I suggest to alter it into “This orange stamp was never issued.”
“The stamps were issued on 18th November 1884 when the first postal service was created.”
This is probablycopy&paste from #1, 2 texts and should be deleted.
These high value stamps were just paper labels when they reached Inchon by 1885.4.5.
To reimburse the printing costs, the korean govt. sold the unissueds by 2 Feb 1886 to Carl Wolter&Co. (Sechang Yanghaeng) of Chemulpo, which in turn sold them to the stamp trade.
