Months before the Monroe County Sheriff's Office issued a warning about fake bills, the Key West Police Department made a similar public service announcement.

Funny money from Hollywood has made landfall in the Florida Keys.

According to the Monroe County Sheriff's Office, a slew of fake bills used in blockbuster films were recently spotted circulating in the area, most notably in the Lower Keys and Key West.

"The $100 bills are marked as fake, stating they are to be used only in making motion pictures, but they may look accurate at a casual glance," officials said in a Nov. 3 social media post.

Due to the phony money currently in circulation, the sheriff's office is encouraging everyone in the area to "double-check any bills you use/receive."

"Please help us spread the word!" the office added.

The Monroe County Sheriff's Office did not immediately respond to USA TODAY's request for comment on Wednesday afternoon, Nov. 5.

Key West Police Department issued similar warning in September

Months before the sheriff's office issued a warning about the fake $100 bills, the Key West Police Department issued a similar public service announcement on Sept. 23 about $20 bills.

"Check your twenties! Some movie prop bills have made it into circulation!" the department noted. "Though they’re marked 'for motion picture purposes,' They can fool you. Oh, and if Andrew Jackson has a smirk, that’s another clear giveaway!"

According to the department, a local businessman alerted the agency of a fake bill "in his till" and asked if they could issue a warning.
