More dangerous than the "locals" are the commemorative stamps which certain impecunious Governments issue with the idea of attracting philatelists.[1] These stamps invariably bear exquisite designs, and are usually current for a limited period. Their appearance is heralded with much beating of drums, and the idea is carefully spread abroad that only the earliest purchasers will be able to secure copies. As a rule these labels are printed in millions, and are often sold to large buyers under face value. The proceeds go towards making the country solvent, or in providing for palatial postal headquarters. Of course, such stamps can hardly be considered postage stamps, as the number used for postal service is but a minute fraction of the whole issue. It is on these grounds that the wise collector should refuse to treasure up labels, the main purpose of which is to amass money for an unscrupulous Government.

[1] Some commemorative stamps are, of course, issued in a purely legitimate way, and must not be confused with the above.

The objection to commemorative, or perhaps it would be better to say speculative, stamps disappears in cases where the specimens have been through the post. Such labels have franked letters or parcels, and have thus fulfilled the conditions which we demand of genuine used stamps. Unfortunately, this fact has been noted by at least one Government, and in order that its gaudy labels should not be shunned by the collector, it has had some thousands of unused copies specially cancelled in the hope that the obliterations will serve to make them more acceptable. Undoubtedly some of the stamps marked in this way are very attractive; but, of course, they are not postage stamps in any sense, and can thus make no appeal to the philatelist.

A third group of undesirable stamps comes from South America. About thirty years ago a Mr. Seebeck, of New York, entered into an agreement with Ecuador, Honduras, Salvador, and Nicaragua, to supply each of these republics with new stamp-dies once a year on condition that the old dies should be handed to him as they fell out of use. As soon as a set of dies became superseded, he printed from the plates and flooded the market with unused copies. The Seebeck issues, needless to say, are of little interest.

Seebeck is not the only man who has printed from discarded dies; there are, in fact, many types of stamps on the market which have been produced from obsolete plates. Such stamps are known as "reprints," and are worthless except as curiosities. Perhaps the best-known reprints are those bearing the inscription "Heligoland"; but as these labels emanate from the Government printing works at Berlin, and have never been to this little island, it is clear that they have served no genuine postal purpose.

Reprints are difficult to distinguish from the original stamps, but as a rule slight differences in colour prove sufficient clues to their identity. Often the correct kind of paper and watermark are unobtainable by those who print them, and then the merest novice may detect their origin with the aid of a catalogue.

There are so many undesirable stamps to be found on the market in an unused condition that the beginner may feel that the safest plan will be to confine his attentions to obliterated varieties alone. There is much reason in such an argument, but it is not altogether a wise course to follow. Unused specimens, as long as they are issued for genuine postal purposes by reputable countries, are more sought after than those which have been obliterated, and their value is more likely to rise in the future.

One matter which often puzzles the novice is how to decide whether two particular stamps are similar or different. If there is the slightest variation in—(a) Design; (b) method employed of printing; (c) colour; (d) method employed for separating the individual stamps; (e) texture of paper; (f) watermark—then the two stamps may be looked upon as being different, and both should be placed in the album. Certain stamps bear designs on their reverse side—i.e., the horn on early issues of Sweden. Copies both with and without the design should be added to the collection. The addition of advertising matter on the reverse side (see New Zealand issues), however, does not constitute a difference. In the case of recent Belgian stamps which bear the inscription, "Not to be delivered on Sunday," in both French and Flemish, specimens with and without the label should not both be given a home in the collection. Lastly, it may be well to point out that stamps, on paper of various textures, which have been cut from entires, should not be considered as individual varieties, seeing that most Governments are prepared to impress any letters, cards, etc., that may be supplied to them, and varieties of such stamps must be, on this account, unlimited.

When the collector has amassed a number of good duplicates, it will be a wise plan for him to join one of the many exchange clubs. In this way he will be able to turn his surplus stamps into specimens for the collection. The working of these organizations is simple. Each member sends a sheet of his own stamps, with prices marked on them, to the secretary of the club, who places them all in a portfolio which is forwarded to each member in turn. When a member receives the portfolio, he selects specimens at will from any of the sheets, but he generally endeavours to balance his own takings with the takings of all the members from his sheet.
