The Banknote Book Vs Scwpm

On top of share bears comments which I agree with 100% If you have a specialist area - country The Banknote book (Owen) hasn't released yet there is probably a draft copy available to subscribers which you may be able to contribute to or provide scans of missing notes or update serial numbers etc.I have done this and found it most rewarding even learned something along the way. He has some very powerful organizations, dealers , auction houses from around the world etc assisting him as they can obviously see there is room for a better product which can only help their business improve as well.
Peters Banknote museum is truly a fantastic site been able to contribute 16 countries myself and encourage anyone who can help to do so. I also do not work for or own these sites just appreciate them.

Most of my notes are errors, not sure if they are of interest on this site.

My £20 Bank of England triple serial number error note has been PMG Certified, and a article of this error published in Coin World's Feb.2009 edition.

It should also be published in the June edition of Token Publishing Coin magazine in the UK.

A reply I received from the Bank of England investigation claims a sheet of 40 notes may have entered circulation.
In my 8 year search for a second example, I could not locate another.

I also have 2 Pakistan 1,000 Rupees with 2 sets of serial numbers on each note, one note has 2 different prefix letters.
