Stylized head right within a dotted border, Brahmi letter "Pra" on the forehead / Stylized Sassanian altar with the shaft replaced with three dots, stylized Brahmi letter "Sri" above, four characters "Ta-Pa/Ku-Na" (probably should be read counterclockwise from "Sri", giving an inscription "Sri Tapana Ja"). 14mm, 0.71 grams, Multan mint. Fishman/Todd "The Silver Damma" Type M9.

“Tapana” was probably the local epithet of Raja Dahir of Alor (679-712 CE), whose realm encompassed Multan. It is also possible that after the initial issues minted by an earlier ruler named Tapana, with the coins of his successors simply used his name as a part of “frozen” design. 

These coins are studied in detail in "The Silver Damma" by Fishman and Todd, now a standard catalogue for this sort of small silver coinage.
