One of the two varieties of the two-letter series with the numerator not terminated (not closed) with an asterisk.
It is the first of these, with a 7-digit number. Interestingly, in this variety, according to Michael Bishop's findings, despite the seven-digit numerator, its first digit always remains zero, as on the present bill.
The variety is quite rare, with only four series belonging to it: from AA to AD.
The present banknote with the attractive first AA series.
Beautiful state of preservation of PMG 64.
