Laid paper should be similar throughout Philately,
albeit in slightly different forms due to the lines of wire in the paper mould.
Imagine it like a fly wire screen, with slightly darker lines (vertical or horizontal) appearing parallel.
I have no information on Hyderabad laid paper,
they should be noticeable to the naked eye, if not take a suspected item, and place in a small dark bowl of COOL water.
Note: be aware not to confuse with BATONNE paper
Hanging chads are experienced throughout most countries stamps.
