All three represent same note. 20 year lottery bond from October 1st, 1952.
N#389775 tries to combine different year issues in same page. It includes 1952 year bond too. Page misses that 1952, 1953, 1955 and 1956 used different obverse designs and different layout. 1954 colors were different. 1957 had different period and every issue has different demonetization date. Maybe move its 1952, 1953 and 1955 users to dedicated pages. If there are any. I can give links to 1953 and 1955 pages, if required. But if there were 5-year lottery bonds issued in 1952, 1953 and 1955, page is probably correct.
