W. S. Fowler.—The first postage-stamp ever made was the 1 p. black of 1840. It is sold for 8c. The 1 p. red was used from 1841 to 1880. There are many minor varieties, some of which are rare.
E. P. Noyes.—The silver dollar does not command a premium.
J. S. Green.—No premium on the eagle cent. The Dutch penny has no value in the U. S.
W. H. Kerr.—The two Siam provisionals, 1 att on 64 atts and 2 atts on 64 atts, are worth 10c. or 15c. each. The other stamp is a "sick-fund" stamp from Germany.
C. C. Perpall.—The difference in the stamps is caused by imperfect printing.
Ash.—The $3 gold pieces do not command any premium. The dates given are the common dates.
M. C. W.—The two stamps are revenue stamps from Bosnia. They cannot be used in payment of postage. Embossing was described in the last number of the Round Table. Stamps vary in value from year to year, and even month to month. Generally there is an increase year by year, but in a few instances they decrease in value. No catalogue can fix prices, and the same issue may be cheap or dear, according to the condition of the individual stamp.
