Franklin D. Roosevelt and his Secretary of the Interior, Harold L. Ickes, became APS members in 1940.

● Original issue date: February 1868
● Face value: 1 point
● Image: Benjamin Franklin
● Rarity Type: Z-Type Grill
● Quantity on hand: 2
The Benjamin Franklin Z Grill, or simply “Z-Grill”, is a February 1868 United States Postal Service 1-cent stamp depicting Benjamin Franklin. While stamps of this design were common 1-cent stamps in the 1860s, the Z-Grill features a so-called “Z” grill that presses into the stamp, creating tiny indentations in the paper.
The ones with the D and E grids quickly replaced the “Z” pattern, which is distinctive among grid templates used by the Post Office because it cuts horizontal ridges into the stamp rather than vertical ridges. The stamps were postmarked in mid-February.
The purpose of the grilling is to allow the cancellation ink to be better absorbed by the stamp paper, thus preventing the reuse of the stamps by washing out the cancellation marks. Grills were found impractical to use and were phased out after 1870.
There are only two known 1868 1-cent Z-Grills, both with cancellation marks. The New York Public Library owns one copy as part of the Benjamin Miller Collection. That leaves only a 1-cent 1868 Z-Grill left in private hands.
Stamp trading platform Mystic Stamp Company acquired the privately owned 1868 Z-Grill in 1998 for $935,000. Zachary Sundman, son of the company’s president, Donald Sundman, traded the Z-Grill for a piece of four upside-down Jenny shoes in October 2005 with stamp investor Bill Gross for an estimated $3 million.
The two surviving Z-Grills were on display at the National Postal Museum from May 27, 2006, to October 1, 2007.

Today, the surviving Boys in Blue are still attached to the yellow envelope in which they were originally mailed, handprinted with “Pay”. In 1981, a German collector acquired it for $1 million through dealer David Feldman.
In Scott’s Blue Boy catalog listing from 2013, dashes appear in the value column instead of numbers, indicating “lacking or insufficient information to establish a usable catalog value”. [5]

They came to be known as “missionaries” because they appear mainly in the letters of missionaries who worked in the Hawaiian Islands. Only a handful of these stamps have survived to this day, so they are one of the rarities of philately.

A Comprehensive Guide to Evaluating, Buying, and Investing in Rare and Precious U.S. Postage Stamps

U.S. Postage Stamps

Next, we’ll delve into the basics of investing in valuable U.S. postage stamps, ensuring a comprehensive understanding of this exciting field.

Condition and Rarity

The condition of a stamp plays a vital role in determining its value. Look for stamps with clear impressions, bright colors, intact backing (if applicable), and minimal damage or defects. Rarity is another key factor. In general, stamps produced in limited quantities or with unique variations are more valuable.

Neat, bright and original colors

Collectors generally prefer fresh and vibrantly colored stamps with crisp original engravings and images over stamps that have faded from exposure to water and sunlight.

Stamp History and Issue Dates

Stamps are like precious cultural relics, and philatelists are like archaeologists. Typically, stamps issued before the end of the 1900s are historically significant and therefore are sought after by collectors and trade at high prices.

Stamp Face Value

Sometimes the value of a stamp is determined by its face value. The higher the face value of a stamp, the more valuable it is. However, this rule doesn’t always apply to U.S. postage stamps, as rare stamps like the one-cent Z-Grill stamp and the two-cent Hawaiian Missionary stamp are worth a lot despite their low face value.

Complete Part

Stamps command high prices only if their designs and perforations are intact. A stamp with missing parts will have less value regardless of its availability (i.e., even if it’s fairly rare).

Unique, Neat Unmarking

An antique stamp still embedded in its original envelope with a special cancellation mark will be more expensive and more desirable than regular stamps. This tendency was responsible for the high cost of the Alexander Blue Boy. So it pays to leave a stamp on the original package or envelope.

Rare Error

An unusual error, such as a missing colour, feature, or wrong inversion due to a production or printing error, can greatly increase the value of a stamp. The Inverted Jenny stamp and the Inverted Declaration of Independence stamp are worth far more than their “perfect” counterparts.

Perfect Piercings And Ridges

Most of the time, the more neatly a stamp has perforations and ridges, the more valuable it is in the philatelic world. You can observe the pictures of B-Grill and Z-Grill for a better demonstration.

Minimal Creases And Damage

Bending and creases can seriously reduce the value of a stamp. So, make sure that the stamp you buy has as little wrinkle as possible and protect it thoroughly to prevent further damage.
