Along the bottom is Qur'an 48:1 followed by something else that is too worn to read. Better photos might yield results. At the beginning is what looks like 2021, which as you say might be the date 1202 written in reverse. Somehow I doubt that this is that old, but I may be wrong.
Along the top is in fact a Persian inscription. I have seen these copied on to kaskaras before but I cannot remember where. These were presumably copied to give the piece some kind of aura of prestige, not as historical inscriptions.
It begins
... در زمان دولت سلطان شاه
'In the time of the reign of Sultan Shah ...'
Again, the rest is too worn to read, though better photos might help. As I said, this should not be taken as an historical inscription
