Automated stamp recognition

I was recently reading a research paper about automated stamp image recognition, when it hit me that this is one of those situations where smart IT-guys (like yours truly, LOL) are often building tools that might not necessarily serve the hobby. If software automatically identifies a stamp in second or two (and even faster), what is there for the collector to do? Take a picture of a stamp, let the program identify it, and then place the stamp into an album? Ask me, but that’s not how you become or enjoy being a stamp collector.

A modern Soviet forgery

I was working with my Russian and Soviet collections last weekend, and upon sorting through a small accumulation of postally used Soviet definitives, I came upon a specimen which appeared a bit odd. Upon closer inspection, I found out that just about everything on this specimen was wrong.

Is it OK to give negative feedback?

Over the summer I’ve been feeling random stings on my heart when filing public reports about the quality of stamps sent for my exchange. I don’t know if it’s part of the Finnish behavior or something more widespread, but I find it very hard to to give (verbal) negative feedback even when I know it’s justified and should be done.

SCB Summer Camp: Filling spaces project

I’m keeping a short ’summer break’ from actual blogging and focus on working my collection and my stamp exchanges for the next month or two. Two frequently asked questions relating to my exchange are “Can you tell me what specific stamps do You need from country X” and “Do you have these…”. Well, this ’summer project’ is all about it. Instead of listing everything I have/need (both which would be a lifelong task), I’ve decided to to narrow the focus in one small (but very dear) niche: European definitive stamps.

Some unissued Russian Civil war era stamps from Armenia

I had an unexpectedly busy weekend due to an work related crisis, and thus had to push down my ’stamping plans’ considerably. So instead of digging into big pile of Nepalese stamps that’s been waiting my soak tray for several weeks, I started sorting a notably smaller lot of miscellaneous Europe. And there I found a couple of Armenian stamps from the Russian civil war era worth sharing.

The unidentifiable uglies – or how I deal with stamps of Indian states

Though I’m quite knowledgeable about various worldwide stamps, one of those areas that give me a cold sweat are stamps of various Indian feudatory states (aka.the uglies). For the past week I’ve been going through a small pile of new additions from various Indian states, and here’s some of my thoughts about them in general, as well as few ‘tough nuts’ to identify.

Indian Capital of Asoka Pillar official stamps

Without a doubt, one of my favorite Indian stamps are the officials depicting the Lion Capital of Asoka. My love/hate relationship with these stamps goes back to my childhood, as back in the 1980s these stamps were substantial part of every ‘kiddie stamp mixtures’. A bit surprisingly, these seem to have become much less common since.

New perforation finds on Liberian stamps

On 1970 Liberia issued a set of stamps six stamps and a miniature sheet commemorating Paintings of Napoleon. All major stamp catalogues agree that the stamps are perforated 11, whereas the sheet is imperforated. With these facts stated, I noticed something that did not fit the story when working on a bunch of these lately.

Good buy vs. bad buy

Over the past month I’ve been corresponding with fellow stamp collector from Poland, and one of the topics we’ve discussed in more detail has been the quality of stamps lots available (on the Internet). As I lately acquired yet another ’small bulk lot’ of stamps to work on, I thought I’d share some statistics about it, and what in my humble opinion separates a good buy from a bad one.
