As I’ve got into studying Nigerian stamps, especially the issues within the time of the British Empire, I’ve realised that watermarks are really important. They can make the difference from a common, low-value stamp and a rare, high-value one. I know this likely applies to stamps of many, many countries.
As I didn’t want to use watermark fluid and didn’t fancy spending £200 on a watermark detector I thought I’d try and find another method of making a watermark visible when it wasn’t just to the naked eye.
This took me into the world of scanning, which I’d already realised was the very best method of making an image of a stamp for a webpage or for selling on Ebay.
I’ve had some success with the scanning method although I reckon I’ve got some way to go yet to see the watermarks on a wide variety of mint and used stamps.
Go to Stamp Watermarks – Using A Scanner to see how I’ve been doing and let me know if you have any better ideas.
