Fivers

The answer to the crossword question “Fivers is ABES” is most likely referring to the fact that “fivers” is a slang term for a five-dollar bill and “Abes” is a nickname for Abraham Lincoln, who is featured on the front of the $5 bill. Therefore, the clue is pointing to the fact that “fivers” can also be called “Abes” due to the image of the former US president on the bill. Alternatively, it could be suggesting that “Abes” is a slang term used for any type of five-dollar bill, not just ones with Lincoln’s image on them.
