The fifth stamp in this series is the 100 Mon. As with the 25 and 50 Mon stamps, this rose, white and blue stamp was never issued and therefore any stamp claiming to be postally used has a fake cancellation. The stamp is designated Scott #5 and Minkus #N5. The stamps were produced in 1884. Black and white images are from Brady-Tyler and colour images are from MikeG Canada (Stampboards) and other sources.
The Catalog Value as shown by Stampworld is 30 Euro for Mint. No Watermark and perforated 8½ to 10.
