I have an interesting dollar bill that has ink bleeding through from the back to the front. Any idea how much this is worth OR where I can post it to find out more? Notice a "normal" bill is on the left, but the other one is on the right. Thoughts?
It's called an offset transfer error. It's a pretty good error, worth ~$40. We do have a 'Paper Money' sub-forum here too, so you're in the right place.
FYI: Your not seeing ink bleeding through. You are picking ink up from the sheet of bills underneath this one. The farther down the stack, the more this is possible. It's due to all the weight above when the ink is not dry.
