I don’t think it is the “THEN NOW ALWAYS” chip. I don’t have the $25 in my collection. I must have picked it up for someone and submitted it to the “Guide” before I mailed it off. However, I do have a $2.50 and a $5 from that series, and both sides are the same. Also, if the $25 had a different image on the reverse, I would have submitted it.
