I assume they were sent into the Patent Office to get the cards trade mark on the design. The Patent Office also gives trade marks and is officially called the US Patent and Trade Mark Office. The Patent Office would have required an example of the product or design art to be sent in to be inspected, registered and filed. They used to require a model of an invention be sent in before the inventor could get the patent, though they no longer do this. The Patent Office would require one example of the product or design, and I assume Goudey sent in only one of each card.
