Question
I'm in possession of a contemporary (US currency) dollar bill where the green ink from the reverse side has bled through to the face of the bill. I've never seen this happen before and was wondering whether this obvious error has served to increase the value of the bill to collectors.

Answer
Hi Larry, Error value depends on type and extent of the error as well as amount of folds or wear and collector demand. This may be worth about $10 or more.
