At 20mm, the denomination will be 2 pai, KM/Y# 35. The date is actually on these coins twice: on the obverse, the AH date is inside the toughra, on the bottom line; from your scans I can read 132X (I can't make out the last digit). The regnal year appears on the reverse, at about 7 o'clock on your picture, which appears to be "40" (though again, it's not quite clear enough).
If the regnal date is in fact "40", then the year of issue should be either 1323, 1324 or 1325. Remember that some Hyderabad numerals are slightly different to regular Arabic numerals; check the table in the front of your Krause to see the differences.
A small number "92" inside the large loops of the toughra is not part of the date. This "92" appears on many Hyderabad coins, but nobody seems to know why.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
