“Phoney as a three-dollar bill” (“Queer as a three-dollar bill”)

Three-dollar bills were printed by various states in the 1800s, but there has never been a U.S. three-dollar bill. There are U.S. one-dollar bills and U.S. two-dollar bills.
 
“Rufe Davis describes a certain ham: ‘Phoney as a Three Dollar Bill!!!’” was cited in Hy Gardner’s “Broadway Newsreel” column in the Brooklyn (NY) Daily Eagle on March 19, 1937. “Rare as a three-dollar bill” was cited in a 1942 newspaper and “queer as a three-dollar bill” in a 1943 newspaper. The expression “phon(e)y/queer/strange/rare as a three-dollar bill” means something unusual or fake.
 
“Queer/strange as a three-dollar bill” also referred to homosexuals by at least the 1960s.
   
   
Wikipedia: Fake denominations of United State currency
$3
Although various US states printed $3 bills before the unification of the currency, no US$3 bills have ever been printed. However, various fake US$3 bills have been released over time, generally poking fun at politicians or celebrities such as Richard Nixon, Michael Jackson, George W. Bush, both Bill and Hillary Clinton, and Barack Obama in reference to the idiomatic expression “queer as a three-dollar bill” or “phony as a three-dollar bill”. In the 1960s, Mad printed a $3 bill that featured a portrait of Alfred E. Neuman and read: “This is not legal tender—nor will a tenderizer help it.” Mad writer Frank Jacobs said that the magazine ran afoul of the US Secret Service because the $3 bill was accepted by change machines at casinos.
