Are any of these actual Errors, and if so, are they worth anything? First Note - Is this an "Offset Error" or something of the sort? Second Note - The last Serial # appears to be cut off. Third Note - The last Serial # appears to be falling off a cliff. Fourth Note - There appears to be a white empty space on the left side of the picture of Ben's neck, to the left of his chin. It's just an empty space and looks like a printing error of some sort. The note is in almost uncirculated condition, no folds, super crisp and the only "wear" appears to be from counting machines. Fifth Note - It's hard to see in the picture but the "K" after the right side Serial # appears to be extremely lightly printed. Also, the note is so extremely off-center in terms of the printing - the front more so than the back.
1st - looks like wet ink transfer from another bill in the stack. However could be close to the last wet ink transfer before all extra ink was gone, but I don't think so. 2nd - A very, very minor light inking or missing ink. 3rd - This is from a counter that hasn't reset properly. Very common 4th - Assuming it isn't a scrape on the bill it is probably some missing ink. Also very common. 5th - Really can't see the light inking in the photo. As for being off center, I think this is within BEP guidelines. All the above are my non-expert opinions, and I would deem all of the notes spenders.
IMO none of them are significant enough to add any value above face. Having said that, I'd offer you $350 for all of them. LOL
