Just yesterday, I was offered on this Uruguay "solid number 05555555". I was told that the first zero can only be 1 or 0. The highest serial number is 10 million ( 10,000,000 ). This is quite similiar to the early Brailian currency which also use such numbering system.
Here is the picture of the banknote in question ( 05555555 ). I found another banknote with serial number with the 1 in front and it confused me further since the highest number can only be 10,000,000.


Here is my Brazilian solid 0555555 which I acquire earlier using the same numbering system.

Now the question, is whether Uruguay uses the same numbering system as Brazil. If it is, this Uruguay note is considered a solid 555555 since it is impossible to have a full straight 55555555 note. Can anyone help me on this question ?
Thanks in advance.
