Let me add this to the conversation. On July 2, 1894, the United States Printing Company became The United States Playing Card Company. Why did they wait 4 years to start date coding? Nothing I could find in their history points to an event to start coding their cards. Production didn't change, their new factory in Norwood would not be in production until 1901. Why the change? It seems like the coding would have started after the name change. Thoughts?
hi,NCC1888
My opinion is that it's because the number of production has increased.
USPCC DATE CODE is printed with alphabets and numbers. Everyone ignores the numbers, but experts must have noticed that the numbers increase in proportion to the number of products produced.
The letters represent the year of production, and the numbers represent the paper number.
A paper number is a number assigned to the paper roll that is the raw material for Playing Cards, and is a quality control number assigned to avoid confusion at the production site.
In the 1800s, the quality of paper used as raw materials varied, and it was a matter of luck whether you received high-quality paper or low-quality paper. This problem was a problem faced by all manufacturers, not just USPCC. Therefore, high-quality paper was used for high-quality decks, and low-quality paper was sold as cheap decks such as Steamboat. Advertisements at the time listed various stock names and finish names, but these were just slogans to promote quality.
Around the end of the 1800s, when production numbers were low, it was deemed sufficient to use only a copyright notice and date, but as the variety of decks became vast, problems such as material errors increased at production sites, making it necessary to strengthen production control.
In addition, in the 1890s, there was fierce competition among manufacturers for copyrights and consolidation such as corporate acquisitions, and the rampant use of copied products was also a problem due to the recession caused by the economic depression.
I believe that the USPCC DATE CODE was introduced on a trial basis to solve this problem.
At the time, there were very few ways to prove that a product was a company's own product.
Therefore, I assume that the introduction of this system was done behind the scenes.
For example.
If there was a code D89, it would mean 'a deck made in 1901 from paper rolls of paper No. 89'.
(By the way, this is different from a lot.)
Later, after 1900, manufacturers under the USPCC voluntarily introduced the USPCC DATE CODE.
However, this caused the DATE CODE to enter a period of chaos from 1910 to around 1930.
If the Playing Cards market size in the US had not expanded, there might not have been a USPCC DATE CODE.
These are my opinions.
