what is a 1907 dollar bill from Chile worth??

Answer 1

First, Chile has never issued banknotes denominated in dollars.
Second, the most common 1 Peso banknote from Chile dated 1907 (and this is what I assume you are talking about) is listed in the Standard Catalog of World Banknotes as being worth between US$2 and US$35, depending on condition.
Your note would have to be like new to be on the high end of that range.
