USA 1$ Bill Size [gelöst]

I recently acquired these two 1$ Notes both 2003 but when one is put on-top of the other they are of Different Sizes the B is 156 x 67 and the F is 154 x 65 is this Normal for US Bank Notes I thought I had gotten hold of a Forgery but I could be wrong.
This Arose my Curiosity as I have other 1$ Bills so I measured some of these and (156 x 67 2 , 156 x 66 , 155 x 65 and 155 x 65) was the Result is there a +/- Figure for US Bank Notes and are these within that Tolerance my Thanks for Advice and Knowledge in Advance.

Shrinkage over time especially if they got wet plus wrinkles could account for the differences.

​I agree. Plus money gets left in laundered pocket, the notes go through dryer cycles (& their composition is called 'rag' referring to the cotton added, so its no wonder they shrink).

Also, more collectible (decades old) banknotes may have been trimmed or "processed." Trimmed just means that nicks or slight edge tears are cut off the boarder to increase BV.

Sadly "processed notes" means that older circulated notes which may be VF to EF were often pressed by irons to remove wrinkles. The paper usually darkens, designs lose contrast (colours fade) & while the note may appear flat (wrinkle free), it has lost its embossing & other qualities advance collectors seek.

Thank you Both for your input it looks like the Notes I Have are all Genuine though not worth a lot bar for 2 of them that are in UNC Condition I do have 2 ,5 ,10 ,20 ,and 100$ Notes that are in UNC that are the Correct Size but as these are of a higher denomination I presume they are like our £10, £20 and £50 looked after a bit better .

I would just like to add an observation, that the design has also shrunk in this case, which you see when comparing the black vertical frame lines of the two notes on the first picture. They are almost aligned on the right, but on the left the lower note is obviously shorter.

I have a couple of Canadian notes that appear to be shorter as well, but I will look at them again to see whether it's "shrinkage".

If the notes were cut shorter by even 1 mm, it would add up to a full cm on a plate of 10 notes, so a whole redesigning would be necessary.

Good point but that would also be the case if the size difference were only due to wrinkling. It does "prove" however that the bills weren't originally cut smaller.

​Yes, that's where I should have been more precise. The fact that the design looks smaller is evidence that the note "shrunk", and that it was originally the same size as the other.
