A bourse is the public area at a coin show of any size where the
buying and selling of coins,paper money, exonumia (medals and tokens),
books, and other items takes place.
According to Merriam-Webster, "bourse"
is also the name for a European stock exchange and literally
means “purse" in middle French.
In a typical coin
show bourse, dealer tables are formed into several large rectangles,
splitting the floor and creating aisles for collectors and other
attendees to walk and view the dealers’ inventories.
