I have been asked about the various monetary designations and symbols that appear on the chips and plaques from India Casinos.
Here is the clarification.
1. RUPEE SIGN -The Indian rupee sign (sign: ₹; code: INR) is the currency symbol for the Indian rupee, the official currency of India. Designed by Udaya Kumar, it was presented to the public by the Government of India on 15 July 2010, following its selection through an "open" competition among Indian residents. Before its adoption, the most commonly used symbols for the rupee were Rs, Re or, in texts in Indian languages, an appropriate abbreviation in the language used.

OLD SYMBOL RS and the new one

2-The INDIA NUMBERING SYSTEM is used in the Indian subcontinent to express large numbers. The terms lakh (100,000) and crore (10,000,000) are the most commonly used terms (even in English, such as in a local variety called Indian English) to express large numbers in the system. For example, 150,000 rupees in India is referred to as "1.5 lakh rupees", which is written as 1,50,000 rupees; 30,000,000 (thirty million) rupees is referred to as "3 crore rupees", which is written as 3,00,00,000 rupees with commas at the thousand, lakh, and crore places.

A CRORE denotes ten million (10,000,000 and is equal to 100 lakh in the Indian numbering system. It is written as 1,00,00,000 with the local style of digit group separators (a LAKH is equal to one hundred thousand and is written as 1,00,000). ( from Wikipedia)
