Dating Old Postcards

Real Photos         Curteich

Got a Main Street, USA postcard that pictures late 30s cars and has a 1939 postmark? For us, that's close enough.

For the millions of postcards in existence that are not so easily age-defined, we consult the painstaking research of experts in the field.

Listed below is a portion of the knowledge base that exists to help in dating old postcards. Hats off to those who compiled this information. It is invaluable to collectors and dealers alike.

Included are those references we consult most often. We hope you find them helpful.

Curt Teich Postcards

Compliments of the Curt Teich Archives at the Lake County Museum ©1994, The Lake County Museum

The first series of cards printed by the Teich company used numbers only and ranged from 1— 14989.The production dates were not recorded by the company at this time, but from copyright dates found on some of the cards, it has been determined that these cards were produced between 1900 and 1908.

The next card series began with either "A" or "R"* and were numbered from 1—124180. From 1908 until 1913 production dates are not clear and were determined by copyright dates found on a few of the cards. These numbers and dates should be used as a guide. After 1913, dates began to appear occasionally in the order books kept by the company and from 1922 on, production dates were well documented.

Year Production Numbers:

1908-10  A1
1910   A19922
1911   A22998
1912   A32000
1913   A32236 —A45599
1914   A45600 —A53999
1915   A54000 —A61999
1916   A62000 —A71999
1917   A72000 —A77320
1918   A77321 —A77481
1919   A77482 —A81999
1920   A82000 —A83599
1921   A83600 —A87975
1922   A87976 —A92873
1923   A92874 —A96826
1924   A96827 —A102410
1925   A102411 —A107826
1924   A107827 —A112867
1927   A112868 —A118311
1928   A118312 —A124180

An "-N" after a number indicates it was a reprinted card. Any other alpha character after the number indicates it has more than one subject listing or the same number was used on two different views. (This is mainly found with the very early Teich postcards and with V.0. Hammon postcards.)

*There are a few hundred cards ordered by the Woolworth company that begin with a "W" instead of the more typical "A" or "R". It is believed that in some cases the same view was ordered by another company and the card was printed with "A" or "R" preceding the number. A small number of cards also filed with this series begin with "BS," "DT," "RG," and "RT." After approximately 1924, the "A" or "R" may not appear on the card at all.

During the years 1929 and 1930, another new system was started. The company used a "-" followed by the year:

Year Production Numbers
1929   1-29 —6262-29
1930   1-30 —2934-30

In the middle of the "-30" period, the numbering system was again changed. A letter would denote the decade ("A" - 1930s, "B" - 1940s, "C" - 1950s, "D" - 1960s, "E" - 1970s) and the number before the letter would indicate the year within that decade. Thus the next card printed after 2934-30 was 0A2935. In 1931 another letter was added after the decade letter. This indicated different printing processes. An "H" was added if the card was printed using the "Art Colortone Method" (linen cards). A "K" was used to indicate "Curteichcolor" which is a chrome postcard printing process. From the 1930s through 1970s the following numbers were used:

Year Production Numbers:

1930   0A-2935 —0A-5363
1931   1A-1 —1A-3637 1A-H1 —1A-H565

* In 1974 the Teich Company was sold to Regensteiner Publishers also in Chicago. The Teich Company continued to operate in the same building and continued printing Teich postcards until 1978 when the plant closed. The "ED" series postcards are international size and are printed as Curteichcolor 3-D natural color reproduction.
