H. B. Thaw.—The Bloods Penny Post is catalogued at 50c. There are three varieties of the Bloods Despatch worth from 15c. to $4 each. The Adams Express is not a stamp. It is probably a trade-mark.
R. Craig.—State Revenues, as a rule, are collected only in the State using them. General collectors do not buy them, and consequently they are not catalogued.
A. Lowkowsky.—The letter-sheets will no longer be made. There are eight main varieties—series 1, 2, 3, 4, 5, 6, 7, and the first issue without series number. They are not classed as stamps, but as envelopes, and envelopes are not collected as generally as adhesive stamps. I believe you can buy the $3, $4, and $5 Columbian stamps at face from the Washington, D.C., Post-office.
R. G. Hughes.—It is a Colombian revenue stamp. These stamps are not generally collected except in Colombia, and hence no value can be given. Your sketch is admirably well done.
R. Moody.—The stamp is the 3c. 1869 U. S., and is sold by dealers at 2c. The coin has no premium.
Lewis E. B.—If the coins are in mint condition the dealers will probably buy at a premium. If not uncirculated they are worth face only.
L. Kenton.—The coin and bank token do not command a premium.
P. B. Evans.—The 10c. U. S. you mention is the 1861 issue if not grilled. If grilled it is the 1868 issue. Your questions as to values have been answered several times in this column. You can get a late catalogue of any dealer at a small price.
M. N.—If in mint condition the dealers will buy, otherwise they are worth face only.
Robert Craig.—Not worth more than face.
