World Banknotes

State Bank of Pakistan, colour trial 1000 Rupees, ND (1988), serial number A0000000, no signature, none of the overprints or perforations you might expect, a single slightly odd horizontal fold, which looks like it might have been in the paper before the trial was printed, thus about uncirculated and very rare
TBB B228t, Pick 43ct £2,000-£2,600
