See the spike above "YE" of the YEAR and also a similar spike exactly opposite to it at the other end of the coin to the right side of the number 1. What type of error is this?
I don't think you know what you are talking about, first see the actual coin and then post your comments
I think it is a die deterioration issue. Sort of like a Cud. Those coins from India have all sort of small issues as a result of overused and worn dies. They have a mintage of over 120,000,000 so those dies took a beating. 1 Rupee (75 Years of Independence) - India – Numista It falls under the Die State category Mint errors are unintentional deviations from the Mint’s intended production that occur during the manufacturing process — such as off-center strikes, double strikes, wrong planchets, or broadstrikes. They are usually one-offs or extremely rare, and each coin is unique in its appearance. Varieties are intentional or naturally occurring differences in the dies used to strike coins. They can be subtle (e.g., different mintmark shapes, missing design elements) and affect every coin struck from that die. Examples include the 1982 Large and Small date nickels or the missing buffalo leg on the 1937 Buffalo nickel. Die states describe the condition of the dies at the time a coin is struck. Dies change over their working life — early die states are fresh and produce sharp, clear strikes; late die states show wear, cracks, or deterioration, which can cause subtle differences in design clarity or add “die cracks” or “die chips” to the coin.

Hard to tell from the pics, but maybe something with the collar/shoulder that holds the die in. It just looks odd about 180 degrees separation.
It's definitely some issue with the die. I can't say I've ever seen two matching breaks like that. Neat coin.
