Many entities within the British Commonwealth will issue special stamps tomorrow to mark the silver jubilee of Queen Elizabeth II. Though most of the issues will fall into the omnibus category, there will be many different scenes represented.

The Crown Agents for the Colonies have recorded sets for 24 territories. Each will release three stamps, with the lowest denomination in each instance showing a royal connection to the territory issuing the stamp.

Prince Philip visited the more remote areas, and is shown as the "royal connection" unit by Ascension Island, the British Antarctic Territory, the Falkland Islands, Pittcairn and South Georgia. Most other low-denomination stamps will picture the Queen in an official state visit.

The second value of most sets shows an item of the coronation regalia or a related subject. Among the objects pictured are the St. Edward crown, coronation oath, the Holy Bible, ampulla and spoon, spurs and jeweled sword, the Imperial State crown, chair of homage, the sceptre, communion plate and the royal coach.

Top denominations represent a step-by-step retelling of the coronation story, from the departure from Buckingham Palace to the arrival at Westminster Abbey, and from the "recognition" scene to the oath and the anointing; the presentation of the sceptre and rod, and the crowning, and finally the return to Buckingham Palace.

The Pitcairn Islands, in the Crown Agents group, released their three stamps today. Tomorrow's first days will involve the Ascension Islands, Barbados, Belize, Bermuda, Botswana, British Antartic Territory, British Virgin Islands, Cayman Islands, Falkland Islands, Fiji, The Gambia, Gilbert Islands, Hong Kong, Mauritius, Montserrat, New Hebrides Condominion, St. Helena, St. Kitts, Solomon Islands, South Georgia, Swaziland, Tristan da Cunha and the Turks and Caicos Islands.

Brunei, Papua New Guinea and Western Samoa will each produce four stamps that are not a part of the omnibus output, as will Antigua and Seychellis. The cost of each set - excepting Antigua and Seychelles, which had not been reported - is $26.11.

Other Commonwealth areas, repsented by the Inter-Govermental Philatelic Corp., will essentially follow the Feb. 7 issuance date, with more than three values in most instances (plus souvenir sheets). Included are Dominica, Gibraltar, Jersey and St. Lucia. Togo's set appeared on Jan. 10, the Maldives on Jan. 24, and the Isle of Man items will come out March 1.

England has delayed its unit of four special Cornoation stamps until mid-May, to meet the needs of special Jubilee celebrations throughout the summer, and to ensure that summer visitors to Britain can buy the stamps. The delayed issuance has also been linked with a nationwide Jubilee tour by the Queen, starting in Scotland in mid-May.

It isn't certain whether Canada's announced precious metal commemorative stamp covers are philatelic or numismatic. The initial stamps were, of course, printed by authority of the Post Office, and the $1 and $2 Tait McKenzie Olympic stamps used for franking were postmarked Dec. 31 at the Canadian Postal Museum.

But the medallic stamp reproductions (in silver and gold) were produced by the Royal Canadian Mint, have not been "canceled," bringing in numismatics. Curiously, the Italcambio organization, which operates out of Miami, Fla.(essentially a numismatic firm), guaranteed to repurchase the Tait McKenize "Precious Metal Stamp Covers" for the full issue price at any time before Feb. 1, 1978.

A set of the two-dollar value reproductions in silver on "Official Olympic Covers" was priced at $88.50, and the $1 and $2 reproductions in gold - also on covers - cost $575.

Canada's Elizabeth II silver jubilee commemorative opened a busy 1977 stamp-issuing schedule, including 24 commemoratives and 14 definitives. One special stamp will mark the 50th anniversary of the Peace Bridge linking Buffalo, N.Y., and Fort Erie, Ontario. The United States has announced that it, too, will postally mark this golden jubilee.

Canada's low-value definitives will stress wildflowers and trees (one stamp will picture Queen Elizabeth), while the medium values will show street scenes. Denominations are not indicated as yet.

The staff of Linn's Stamp News - with some outside help - has produced the remarkable "Linn's World Stamp Almanac," a 700-page-plus compendium of information which is destined to be a must for everyone wishing an authoritative source for information.

Twenty-five chapters run the gamut of facts, including law and the hobby, taxes as they affect collectors and the trade, postal regulations and the worldwide role of philately. Included are a history of U.S. Postal communications and a discussion of philately and the Bicentennial.

There are also chapters relating to postal administrations, philatelic and dealer organizations, periodicals and literature, and exhibitions and first-day locales. A 56-page index permits speedy access to specific events and individuals.

Linn's World Stamp Almanac is available for $10 from the Amos Press Inc., P.O. Box 29, Sidney, Ohio 45365, or from most stamp dealers.

England will postally recognize discoveries in chemistry with four stamps, due to appear March 2. Prof. Derek Barton's work on conformational analysis will be recognized on the 8 1/2-pence; Sir Norman Haworth's Vitamin C research is stressed on a 10-pence item; Profs. A.J.P. Martin and R. L. M. Synge (partition chromatography) are recognized on the 11-pence stamp, and Profs. Willaim and Lawrence Bragg (father and son) will be honored on the 13-pence for their development of the X-ray photography of crystals (crystallography).

Presentation packs containing the set of four stamps (5 1/2 pence each) and four new postcards - each featuring one of the new stamps - (7 pence apiece) will be sold at most post offices from March 2, and also from the Philatelic Bureau, Edinburgh. COINS

The annual meeting of Assay Commissioners will be held in Philadelphia's Mint Wednesday, after a hectic 20 days, in which the list of individuals honored had to be approved by the Carter Administration.

Those appointed pay their own transportation to Philadelphia, and their hotel bill, and some meals and taxis. Offsetting the time and expenses are the honor and the experience.

Commissioners also receive a striking Assay Medal, and a certificate signed by the President, and attend a get-acquainted party the night before, and an impressive dinner afterward.

In all probability, this will be the final Assay Commission meeting Mrs. Mary Brooks, director of the Bureau of the Mint, will preside over. She has always maintained a special interest in these annual events, and reportedly delayed her retirement plans so that she might enjoy this one.

Mrs. Brooks received the Alexander Hamilton Award last month in recognition of her outstanding leadership. The citation, presented by former Secretary of the Treasury William E. Simon, read:

"Mary T. Brooks, 28th Director of the Bureau of the Mint and only the third woman to fill this responsible position, has provided imaginative and innovative leadership for the Mint's diverse operations, conducted in seven field installations.

"During her two terms as director, the production of United States coinage virtaully doubled, rising from seven billion coins in 1969 to over 13 billion coins in 1975. When the public began withdrawing pennies from circulation in 1974, thus threatening to overburden Mint production facilities, she improvised a public relations program designed to elicit the return of hoarded pennies to monetary uses.

"Mrs. Brooks ably presided over all phases of the unique Bicentennial coinage and medals programs, from the design selection through demand forecasting to automated public sales, and established for the first time a progressive system of audits of the nation's gold stocks in her charge at the Fort Knox Depository. Under her guidance, major numismatic programs multiplied in number, reaching deliveries of over 4 million sets of coins and medals annually.

"Through her keen appreciation of the historic role of the mints and her keen perception of the public's numismatic interests, she opened new medallic and monetary programs and restored historic facilities, to the lasting enrichment of the nation and its citizens."

Ironically, Tresury finds itself with a Lincoln cent glut now, and there have been reports that a number of employees have been released at the various mints.

Lincoln cents accounted for roughly three-quarters of all coins sturck during Fiscal 1976. During the last six months of 1975, the several mints (including West Point), minted about 4.7 billion cents. That would represent over 20 "new" Lincoln cents for every man, woman and child in the country.
