Please check your coin again. It's either not 1952 or not JFK. Kennedy was a junior senator in 1952 and very much alive so he couldn't legally be depicted on a coin. Benjamin Franklin's image was on the half dollar from 1948 to 1963.
The U.S. did not make any $1 bills or coins with that date. Please check again and post a new question.
The question is too ambiguous. Is it about a randomly selected person having twins in 1952 as opposed to another year? The incidence of multiple births has increased over the years as a result of IVF. Does the person (parent) have to be living now so as to be selected? Is it about an individual having twins in 1952 as opposed to other people who gave birth in 1952? For that you need data on twin and other births in 1952 for the whole world. I very much doubt if such statistics are available - certainly not reliable ones.

Please check your bill again. There were no US bills of any denomination dated 1952. The nearest matching date for red-seal $2 bills would be 1953.

Ireland does not use the dollar and never has, so there is no such thing as an Irish 1 dollar coin. Ireland was using the pound in 1952, but there was no 1 pound coin. So whatever coin you have, cannot be either an Irish one dollar coin nor an Irish one pound coin from 1952.
