No. That's an urban legend that began because some people noticed that the new purple bills have the same series date (2006) as the old green and black bills, and they assumed that the new bills' date is incorrect.
However, that's a misunderstanding of the way American bills are dated. Current practice is to issue bills in a "series" that starts with the appointment of a new Secretary of the Treasury. All bills printed during their term carry the same date regardless of when they were actually issued. Henry Paulson was appointed in 2006, so a 2006 series was started. When the Treasury decided to change the $5 bill's color in 2008 Mr. Paulson was still in office so both the new and old bills are part of the 2006 series and carry that date.
It is worth $5.00
I is worth nothing. A dollar store probably made it for a joke.
It's worth $20.
All you have is a regular series 2006 $1 bill with a Santa decal over Washington's portrait. It's worth one dollar.
It's still worth exactly $10.
It's worth exactly 100 dollars.
If you are referring to newer 5 dollar bills with a large purple 5 on the reverse, they are only worth $5, they are simply redesigned to make it harder for people to counterfeit. If you are referring to some other "purple 5 dollar bill" it was altered with when it left the Federal Reserve and have little collector value.
Please post a new question with a description of the misprint.
The 1943 Trinidad & Tobago 20 Dollar note comes in two versions, one green and one purple. Both are very scarce, and valuable in any quality. A Very Fine example would be worth $1,000 (Green) or $1,500 (Purple) and even a Good is worth $450-$500 (either colour).
