In the past few months I have had occasion to examine a large number of stamps, and several collections belonging to members of the "Round Table." I am sorry to say that a great many of the stamps show that they have not been handled with the care they should have had, especially in the matter of hinges, or "stickers." These are seemingly very insignificant things, and any dealer will supply hinges for 10c. per 1000, while for 15c. a very superior quality can be obtained. Home-made hinges frequently injure the stamps through chemicals in the gum or paste making a change in the color of the stamp. Of course the majority of stamps I have seen have been very common stamps, but every collector should take as great pains in the mounting of common stamps as of the most valuable specimens. I advise you to use the best hinges that can be obtained. Their cost is insignificant, and they will save you many damaged stamps. I have sometimes been asked to recommend Philatelic publications. This has led me to investigate as to the number of Philatelic publications that have been issued up to date. I find that their number is at least 16,000, and probably 20,000 in all. Of these about one-half are in the English language, and most of these have been issued in America. Nearly one-third are in the German language. The balance is distributed among the French, Spanish, Italian, Dutch, etc. Most Philatelic journals have ended their career before the end of the first volume, and very few survive a second year. C. C. DUNNING, Wrightsville, Pa., wants to exchange rare coins. J. F. HAMMOND, Harford, N.Y., wants to exchange stamps. J. HALL.--Beware of counterfeit grilled stamps. They are apt to deceive any one not an expert. J. SCHMIDTBERGER.--Only 363 sets of the U. S. State Department $5, $10, and $20 stamps were made. They should be of equal value, but they are not. The $5 is worth the other three together. J. A. RAYCE.--English stamps are often marked by perforations in the form of initials. This is done to prevent theft, as the owners can prove their property. J. O'NEAL.--Your gold coins have no premiums. You can get a coin book through any dealer. B. B. MORRIS.--The 1857 "flying eagle" is worth 5c. if it has been circulated but still in fine condition. The 1856 "flying eagle" is worth $4. SQUIRE REICK.--No premium. READER.--Take the offer of $1 for the 1822 silver half-dollar. You can do no better. A. PARRISH.--I cannot tell you what advertisers mean by "good," but I should say they do not mean uncancelled. R. N. KOFOID.--It is not advisable to take Revenue stamps from legal documents, unless these documents of themselves have no value at this time.
