This is a video of a woman removing the fake numbers from a $10 bill that's been altered to look like a $50. Were those decals? They looked like model airplane decals. Basically the counterfeiters just replaced anyplace it said '10' with a '50'. They did not change Alexander Hamilton's face into Ulysses S. Grant's though, so that's a dead giveaway provided you know who belongs on a $50 bill. I thought it was Reagan. I also thought nickels were the most valuable coin because they're the fattest, which explains how I always got hoodwinked out of my lunch money until I got to college.
Keep going for the video.
Thanks to Inaction, who I'm surprised even managed to send a tip.
