Coin and Paper Money Collecting/Twenty dollar bill



My question concerns a Series 2006 twenty dollar bill which I received from the bank.

The back of the bill is discolored, it is almost a rust color and is not a solid stain acrossed the back of the bill, but more of a weave pattern on the 2 sides and solid inside the oval (picture).

The second odd thing about this bill is that on the left side where the eagle is located is a bleached out thin white line. It begins at the top of the bill and runs down along the eagle's left wing and thru the very edge of the two on the bottom of the bill.

I can supply pictures if you would like.

Any information about this bill would be greatly appreciated.

Thank you for your time.



Without a photo, hard to say, but my bet would be it's been altered, and not a real error. The rust color is likely caused by a bleaching agent, like when your bill was left in a jeans pocket, and went through the wash.  The black ink is not affected by the bleach when the bill is washed. Your bill was likely left in a pocket when it went through the wash and dry cycle. You may want to try two experiments for yourself on two one dollar bills. Take one directly and apply bleach to the back side and see what happens. Take another bill and run it through the wash and dry cycle. Compare the two to your "error" bill you asked about, and let me know. They are still spendable, so don't worry. This would be considered altered and not worth any premium.

Here's link for you to view different types of real error currency and their values.


You may want to check US coins and currency listings on eBay from time to time to see if your currency is listed what these type of items may bring.

Here is a link to find a local shop, they should offer an opinion as to the value at no charge. Always try and get at least two opinions and try and deal with PNG dealers if possible. If you should decide to sell your items to a dealer, remember they will offer about 50% to 60% of the retail value. See:
