How accurate (or inaccurate) are traditional stamp perforation gauges

How accurate (or inaccurate) are traditional stamp perforation gauges

Lately a discussion at SCF caught my attention. The original poster there had noted that the ruler in his Lighthouse/Leuchtturm stamp perforation gauge was not accurate and was seeking for better alternatives. I have for a long time known that traditional perforation gauges are not tools of extreme accuracy, but I have never read a proper study on the subject. So out of curiosity I decided it was high time to check the precision of my traditional gauges. At first I scanned all my three stamp perforation gauges at 1200dpi using a high end professional scanner, then I used Photoshop’s Measurement Log tool and SCB’s Free Digital Perforation Gauge to obtain accurate measurements from these scanned gauges. Needless to say the results were more than interesting.

Paraguay 1937 Church of Incarnation airmail with strange perf – genuine or fake

Possibly the hardest part of being a worldwide stamp collector is identifying whether or not something is genuine or not, especially when you have got only one copy of a stamp to study. Such is the case of this Paraguayan airmail stamp that got me scratching my head for a long time.

Random notes on Guatemalan stamps

This week I’ve worked my way through a pile of stamps from Central and South American countries, and above all the stamps of Guatemala have once again caught my interest.

Finland Independence Day Sweepstake: win stamp catalog & stamp mixtures

Finland celebrates it’s 100th anniversary on December 6th, and though I am far from being a patriotic person, I do want to commemorate this special event.  So I am organizing a small sweepstake for readers of SCB.  In addition this is a great opportunity for me to clear some clutter from my stamp desk 😉

Russian Federation 1992 Saint Petersburg local make-up stamps

Russian Federation 1992 Saint Petersburg local make-up stamps

Upgrading a stamp catalog is always a double-edged experience where you win some, lose some. When I upgraded to more recent edition of Michel East Europe catalog, I was very pleased to see that Michel now lists Russian St. Petersburg and Leningrad local stamps of 1992. These were previously listed only with Stanley Gibbons Russia catalog, and as such a lot of collectors (yours truly included) didn’t know what these are, and as such they were often falsely classified or thrown away as bogus stamps.

Beauty and the Beast: Inventorying not just quantity, but also quality

Beauty and the Beast: Inventorying not just quantity, but also quality

What are the odds of discovering a nicely cancelled British stamp? Or Sri Lankan stamp with non-obtrusive postmark? Or Canadian stamp with something other than machine slogan? I am sure most worldwide stamp collectors do agree with me that all above examples are possible, but somewhat scarce creatures. On the other end of the line are stamps from countries such as Switzerland, Germany or Denmark, which are almost always nicely cancelled.

Working with Machin stamps

Working with Machin stamps

Machins. You either love them or hate them.  I have experienced both phases, and I would describe my current relationship with Machins as ‘deep fondness’. My first touch with Machin occurred as a kid when my uncle’s fiancée was in London and sent some mail that were franked with 10½p yellow Machins.   Since then my collection of Machins has grown to fill a single 32 page stockbook.

“Technik und Landschaft” Series

“Technik und Landschaft” Series

Date of  Issue: Aug 01, 1949. Stamps from this series can be found anywhere. One reason for this is that large numbers of some of the denominations have been produced, and another might be that these stamps never expired and can still be used today (this also serves as a reminder that the Swiss currency has been very stable over many decades).  Some of these stamps were amongst the first ones in my childhood collection. I liked them then, and I still do today. I do think that they are beautifully crafted, and in my opinion the design is timeless – it still works today, almost 70 years after they were first introduced.
