I usually keep anything I have received in change like silver certs, red seals, stars etc. This is the coolest one I have found over the years. I received it from a gas station a handful of years ago.
My first saved note, and yes, I know now I misspelled the word professional. I was 18 years old at the time and most likely high.
This note is local to me, therefore some special meaning. I acquired it many years ago from Denly's of Boston. Printed on one side from Berkshire Bank, Pittsfield, Ma. Dated 7/5/1807.
Even though my family never actually owned any stock in Granite City Steel, 3 generations (at least 6 members) of my family worked there from the 1920's to the 1970's, so when I saw that the old stock certificates were available on eBay, I had to have one.
