New Mint-mark of Kolkata Mint ?

Kolkata Mint issued coins with Noida Mint-mark ?

Recently issued UNC & PROOF sets of Comptroller & Auditor General of India, by Kolkata Mint distinctly show Large dot mint-mark of Noida Mint on both coins of Rs. 5 and Rs.150. The circulated coin of Rs. 5 has NO mint-mark : which is the identification of Kolkata Mint !
