National Cash Register (NCR) 100th Anniversary Commemorative Bank

National Cash Register was the premier cash register maker for most of the century. Note on the back it says "NCR U  Established April 21, 1937."  This refers to the date that seven NCR employees formed a credit union with $70 capital. Presumably this bank was created at that time for the credit union, and made as a second edition in 1984 for the 100th anniversary of NCR. Today that credit union is the Universal 1 Credit Union based in Dayton, Ohio and which operates 19 offices and has $275 Million in assets!

The cash register was invented in 1879 by James Ritty who kept a saloon and wanted to prevent sticky fingered clerks from lowering his profit margin. National Cash Register (NCR) took over Ritty's patents in 1884 and sales took off slowly after that. By 1889, they had sold 10,000 machines, but by 1896, they were up to 100,000 - an exponential jump due to owner John H. Patterson developing the market for the cash register. The earliest cash registers at NCR were wood through the early 1890's then cast brass cabinets through about 1918. Later they transitioned to the more modern stamped metal cabinets that were painted to look like wood. During this time they also started offering more high tech (relatively speaking) options such as customer count and cumulative totals. NCR was an early example of flexible manufacturing and could easily respond to changing consumer demand, something which was directly responsible for the astounding variety of early cash registers as well as their toy counterparts. They would eventually grow to represent 95% of the total market.
