In absence of official references, the possible early copper mughal coinage of Kabul is a kind of ink pot

Just a few personal thoughts...
The silver coins struck at Kabul by the early mughal rulers, Babur & Humayun (and Kamran mirza) were tanka or shahrukhi of 1 mitqal were based on the existing central asia standard weight, no copper coins seem to have been struck by a mughal mint at Kabul (?) and my feeling is that small change copper coins were local currencies used in the whole area with various weights according to local policies of amirs and economic variations, validated for use in the city by a stamp “ ‘adl Kabul” .
I don't know if the Agra light and thin coppers maight have been struck too at Kabul?
I have recently seen for sale a timurid copper (likely 850-900 AH, and may be flattened before overstrike ?) with multiple counterstamps; among them : “ ’adl Kabul “ in a square, and “zarb Kabul”
Counterstamps “’adl Kabul 1000 or 1001“ are found on old Suri paisa (+/- dam standard) .
This practice may have been in use at least till the creation of the Ilahi era when a mughal standard seems to have been adopted; half dams dated Ilahi 32 & 33 are well known and in the last 5th-6th years of Akbar reign after the introduction of the tanka / tanki series, official copper coins of Kabul mint are well known but seem to have been struck in small quantities (4 tanki, half and full tanka are rare).
