Old 100 Bill Security Features

So, you've stumbled upon an old $100 bill, huh? Let's chat about those fancy security features it's packing. Grab a coffee, let's dive in!

First things first: Check the date

Before we get all excited, let's make sure your Benjamin Franklin isn't a relic from the 1920s. If it's from before 1996, it's time for a trip to the bank, not a shopping spree. But hey, who knows, you might be sitting on a small fortune!

Now, let's talk security threads

You know those thin, shiny strips running vertically? Those are security threads, and they're not just for show. Hold the bill up to the light, and you'll see a tiny 'USA 100' or 'USA 100' repeated. Try that with a fake, and you'll be left with a very expensive piece of string.

Oh, and here's a fun fact: Those threads are made from a special material that changes color when you tilt the bill. Magicians, eat your heart out!

Meet Lady Liberty

On the front, you've got ol' Lady Lib herself, the Statue of Liberty. But look closer, she's got a little secret. In the blank space between her eye and the torch, there's a tiny '100' or 'USA 100' that's only visible under UV light. Shine a blacklight on it, and it'll glow like a rave party.

And get this, her eye changes color too! Hold the bill up to the light, and her eye will turn from copper to green. Spooky, right?

Don't forget the color-shifting ink

Ever noticed how the numbers '100' in the lower right corner seem to change color? That's not a trick of the light, that's color-shifting ink. Hold it one way, it's copper. Hold it another, it's green. Try that with a fake, and you'll be busted faster than a kid with his hand in the cookie jar.

And finally, the ultimate test

Alright, here's the big one. The ultimate test to prove your bill is the real deal. Ready? Here goes... Try to spend it. If it goes through, congratulations! You've just passed the most important test of all.

But hey, if it gets rejected, don't come crying to me. I'm just the guy who told you about the cool security features. Now go forth, and may your old bills be genuine ones!
