Such marks on Indian coins are called "shroff marks". A "shroff" is an employee of an Indian banker or a merchant whose job it is to test the silver quality of coins their customers give them. Specifically, they were to be on the lookout for plated counterfeits, so the method of testing was usually to make a small punch or drill-hole, just to see if it was silver all the way through or just a thin plating.
In that sense, they function similarly to the "chopmarks" found on Chinese coins, though shroff marks are usually smaller and simpler, and almost always found on the edge of coins.

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
