I have this karshapana, I think Samprati, but I cannot identify it in the Gupta/Hardaker catalog. I found the symbol on the reverse and three symbols on the obverse but I can't identify the one on the upper left (it looks like the legs of an animal but facing left, not right like Samprati's) and I can't find the fifth symbol (there are several punch marks underneath, as if someone wanted to check the metal alloy. The Greeks and Romans used this technique but I have never seen them on karshapana). In the images I include what I was able to find.
