How to tell if it's a real dollar bill?

There should be colored threads mixed in with the linen/cotton blend.

Also (I’m inspecting a bill now), I find that if I run the edge of my fingernail over the heavily inked portions of the bill (like the border), there’s a texture.

Hey Daytona! Long time no see :)

I found, from a quick google search, this wikihow link:

Also, I remember learning that, if a bill is not, copying it with a copy-machine will result in a special watermark over the bill. Not sure if that will work, but it is all I remember from when I visited the mint :s

EDIT: Ooh, that wikihow link is neat. Apparently, looking at it against a light, you will be able to see a special watermark! Neato! :)

I doubt that anyone would fake a 1 dollar bill. It takes $2—$3 for each counterfiet bill to be made.

There are some machines you can buy that check if a bill is real or not.

Only stupid people would try to make fake $1, but there are plenty of stupid people in the world….they sell markers at Staples and pretty much everywhere that sells office supplies, that you can mark the bills with to see if they are real. The markers are very cheap, I think I bought 3 for $1 a few years ago, I had to use one yesterday in fact.

How old are they? (There should be a date on them.) the older bills used to be copyable on a copy machine. Back in the 80’s my little brother got in a lot of trouble for copying 1 dollar bills and taking them to a laundry mat coin changer. It actually worked back then.

@Judi LOL nice

Wasn’t so nice when he got a speeding ticket and a cop searched his car. It was a federal offense and started his criminal career which ended with a crank induced suiacide.
Crime doesn’t pay.
