CHECKLIST OF DATED PRECANCELS KNOWN TO BE USED IN JULY 1938

Jim Hirstein September 2020

1

INTRODUCTION

In July 1938, the dating order of the

Third Assistant Postmaster General took

effect, requiring all precanceled stamps

on packages with more than 6c postage

to include the initials of the user and the

month and year of use. Since then, dated

precancels have been a popular specialty

for precancel collectors. There have

been checklists, journal articles, study

groups, catalogs, and databases that

picture more than 10,000 controls.

The controls were applied in three ways.

Precancels with the city and state already

on the stamp would have the control

added by some type of printing process

(printed dated) or by a handstamp device

(handstamp dateds). In some cases, the

city, state, user, and date were all applied

in the same printing operation (these are

called integral precancels). Some of the

early users did not have any kind of

printing device, so they just used a pen

to write the initials and the date. These

are referred to as manuscript controls,

and are noted in the list by (mms).

This is the third printing to show all

known control initials that were used in

that first month, by any means. By far,

most of the controls were applied by

handstamps. Any printed dated controls

are noted in the list by (PD). Integral

precancels are noted by (int). In a few

cases, the same initials appear on more

than one device in the same month.

There are brief descriptive notes that

distinguish these devices. The note

‘SNIF’ means ‘state name in full’ – it

compares that device with one where the

state name is abbreviated. Some devices

are clearly July ’38 but the user is hard

to read, so a (?) indicates that this is my

best guess at the users initials.

This list has over 1200 entries, but I expect

there are more. Some have probably been

missed, and some have not been found yet.

Some of these are very common and others

are known on only one copy. I continue to

look for July ‘38 and will add to the list

whenever I can, but this is now a pretty good

start.

As always, thanks go to the early collectors,

checklist compilers, and catalog writers who

saved and documented so much of the

valuable information that we can draw upon

today. Many of these collectors are

unknown to me, but their efforts have

contributed to this hobby, and I express my

heartfelt appreciation to all of them.

I will mention a few names from the long

line of contributors to the dated cause. The

original was certainly Rolston Lyon, who

compiled the first checklist of all dateds in

1940. His list was updated by Dr. Jon

Wilson in the 1980s, and extended by my

good friend Earl Ratzer. The study and

information I gained from these pioneers is

priceless. I learned much of what I know

about printed dateds and integrals from Dale

Besom, catalog editor when I found dateds

in the 1980s. The extension of the PSS PD

catalog and the Handstamp Dated Database,

both by Gene Byers, have been most

helpful. Integrals are illustrated in the PSS

Town and Type Catalog, now in its eighth

edition. Manley Behrens and Bob Bartlow

started me down the path of dateds around

1980, and it has led to an exciting and

challenging journey. I hope this checklist

will inspire future collectors to keep looking

for the new frontiers that are still there to be

found in dated precancels.
