I'm looking for some ideas on where to create my next focus in both the book, and in what collectors are struggling with. Please take my survey, you can pick two from the following list, and if you pick "other" please post a message with the topic.

For me, it's color and watermarks. Color, because the same color on different stamps can appear different depending on factors such as the density of the color in a design (the line spacing and depth on engraved stamps). Watermarks are often tough because you don't see enough of it on one stamp to determine, for example, if you have the oval or circular shaped wmk. Same thing with crown watermarks. It is hard to distinguish the details that differentiate similar watermarks.

Florescent tagging. I hate it when tagging is an issue. I don't have an appropriate light source and I prefer not to use album space for stamps that are in all oher respects identical. Watermarks are bad enough. With tagging, even my eyes roll back.

Ok Phil, I have made a posting for this. It's the start of what I'm calling my "Identification Series". Hope it is useful.

I've read it and thank you very much. I had not thought of using fluorescent ink before. With the current flood of counterfit stamps, do you know how they test for tagging? The obvious answer is they aren't tagged, but with fluorescent inks...

Hey Phil, What I have observed so far, is that Chinese and Russian counterfeits do not have tagging. However, I have one "suspect" block I'm working with at the moment, which was supposed to be counterfeit, but I find a luminescent response at 254nm UV. I'm looking further to verify it (I don't have the equivalent modern "known good" stamps, so once I get that I can explore it a bit deeper. However, florescent and phosphorescent inks are not particularly difficult to formulate, and aren't controlled in any way, so their possibility of being present is reasonably high.

I have also been interested in tagging and newer anti-counterfeit technologies which do not work!

Anti-counterfeiting is a little like computer security: it's only a matter of time before someone finds a way to fool it.
