2009 1$ Error Note Help

All banknotes are cut at the mint.
Why it was cut oversize I don't know but it was intentional.

In this case I think the bill was not cut at the BEP (Bureau of Engraving and Printing).

My memory (could be wrong) is that the US BEP sells uncut sheets of various denomination bills and the serial numbers for these collector sheets always start with 99.

So, I suggest this is a $1 bill that some owner cut oversized from a full sheet and submitted it to PCGS.

I have one around here somewhere with a 99 serial number that I received in change a while back.

Edit - appears that nfine and I were typing at the same time and his post beat mine. At least we are in agreement.
