The number you see on the right is code: first number is month; second number is last digit in year; remaining numbers are the individually numbered notes. While confusing, a not never lasted 10 years in circulation. The picture shows the #1 10 Quart note from January 1978. These were made on a yellow green handmade paper. Some had frayed edges. Others were tissue thin while others like thin cardboard. The lonest running series of notes with annual numbers near 1,000 or so in several denominations from 50 Mill to 7.5 Quarts. 50, 100, 150, 200, 250 Mills, 1/2, 1, 2, 5 and 7.5 Quart Notes. None of these are available.
