I guess the easiest thing to look for in our "new" money, would be that plastic strip embedded within the paper. Hold the bill up to the light and it'll be there someplace.
But there is still a lot of "old" money in circulation too.
The bills in the picture above are all genuine, and they are worth face value. Because of their dates, if, IF they would be in mint condition, they would be worth a little bit more. You don't see many old bills today, but when I find one, I'll keep it.
But notice how much darker green and black the bills are compared to today's money.
That's what first caught my eye with the counterfeit 20's we've found here at work.
I was told that one of the local banks gave one of their customers a "bad" Twenty the other day. That's how good these fakes are.
Who knows how many counterfeit bills this dude printed?
