Thanks....I have that bill, but I don't know what a radar is. The bills have been kept in two plastic protective cases. I had them stored in a box for the last twenty years. I finally found the collection again in the basement. I looked for them to show my 10 year old son. I also have some 1954 8-$1 (1 bicentenial), 8-$2, 3- $20, 1- $5 (devil), 1-$10 3-$50 and 2-$100 bills. I guess even in the lean years I still had money.....
