‘If you have a UV light, you can check when year your money was made,’ he wrote.

In a second video the user shows where the year maker is located on transparent art strip on $5, $10, $20, and $50 notes. 

Commenters were amazed and shared more helpful ways to use the small UV light.

‘I literally just tried this and I thought this wouldn’t work,’ one person said.

‘You can also check your carpet for any stains you can’t normally see! It’s a win-win with that UV torch!,’ a third commented. 

Another user revealed that ‘this is how businesses tell if your notes are real or fake.

‘You’d be surprised how many people carry fake ones without knowing (change from 100 etc),’ the person said.
