GPZ was found by quite a few collectors and was well documented/
I beleive there were about 1million notes. The following picture shows the high and low pairs found in block GPW5314 and GPY8652.
You will notice that I picture the notes in pairs exactly 500 apart.
These pairs are actually cut from the same sheet. Notes are generally printed 40 per sheet into reams of 500 sheets. The reams
are then cut into 40 stacks of 500. Two stacks are paired to make 1000note blocks. If a sheet was ruined and replaced then
each 1000note block will contain 1 note from the replaced sheet in both the top 500 and the bottom 500. These same sheet pairs
will always be exactly 500 apart.
