How to Offer Wild Birds Shelter in the Winter

Not all birds migrate south for the winter.  Winter is a hard season for birds, and many risk freezing to death at night. It doesn't take much effort or money to provide shelter for them, and it can make a huge difference to the little feathered guys!

A short history of star notes

On April 14, 1920, the director of the Bureau of Engraving and Printing wrote to the treasurer, Lee McClung suggesting “that the Bureau be authorized to prepare a stock of notes numbered in sequence, distinguished from all other notes by a special letter or character printed before / after the serial number… that these notes be substituted for defective specimens… with notation on the pages indicating the package contained such substitutes.”

The green light to proceed was given. Approval must have been anticipated, because on April 17, 1920 a rush order was sent to the American Numbering Company in Brooklyn, N.Y. specifying eight stars for use on automatic numbering blocks. The Bureau finished the first package with stars on June 20, 1920, and delivered them to Treasurer McClung on July 12, 1910. Thus the earliest possible star notes are those of 1910 with the Vernon-McClung signature. The first pack of stars was numbered * 75612001 A through * 75612100 A and were Series of 1899 $1 Silver Certificates.

It is inevitable that some misprints, smudged notes, or otherwise imperfect notes will be made during note production. At the time of examination, these imperfect notes are replaced by new notes that have a star on one end of the serial number. The percentage of spoiled notes is very small; hence the number of star notes is rather limited. In the early series of our small size notes, the spoilage percentage has been accurately estimated at less than %1 of total notes. No attempt is made to replace any defective note with the same serial number star note.  Star notes also are used to replace the 100 millionth note instead of a note with serial 00 000 000 as printed.
