The New York Herald states that the Duke of York is prepared to sell his very valuable collection of stamps to the highest bidder. Lord Rothschild has made the most liberal offer thus far, but he would prefer to buy the rarest specimens only.

C. E. Abbey.—U. S. stamps are printed on plates of 200 or 400 stamps divided into panes of 100 stamps each. A sheet of 100 stamps as sold by the Post-Office is one of these panes. Every plate bears a number, and this number is printed on the margin of each pane. For instance, the current 2c. red is printed from plates of 400 stamps which, after printing, is cut into four sheets. I illustrate plate No. 112.

I know of no stamp chapter in Newark.

H. B. Thaw.—The 12 sen 1875, Japan, is worth 70c., the 15 sen, same issue, 60c.

L. M. C.—Dealers quote two varieties of the half-dime of 1838, one at 10c., the other at 30c.

A. Whittemore.—No stamp was found in your envelope when opened.

D. C. S.—The stamps are Costa Rica revenues. There are several varieties of U. S. 1c. Proprietary worth from 1c. to 10c. each.

J. K. Morlan.—The current 1s. Great Britain postage-stamp is catalogued at 2c. if used. As there are many thousand varieties of North, Central, and South American stamps, I cannot quote values, but advise you to buy a catalogue.

E. H. Maurer.—The $1 values of U. S. postage-stamps are largely used to pay postage on packages of bonds sent from the U. S. to Europe. The "pink" 1861 is extremely rare. It is a peculiar shade which cannot be described in words.
