- Ten Rs Ex Rare 6" o Clock Error Coin Akam Year 2026 Calcutta Mint RBI Mistake Coin
This is an exceptionally rare Ten Rupees error coin from the 2026 vintage, minted at the prestigious Calcutta Mint under RBI (Reserve Bank of India) authority. What makes this piece truly extraordinary is the distinctive "6 o'Clock Error"—a remarkable minting anomaly where the coin's reverse is rotated 180 degrees relative to the obverse, creating a highly sought-after rotational error that collectors prize above standard issues.
Graded in UNC (Uncirculated/New) condition, this specimen exhibits pristine quality with no signs of wear or circulation, maintaining its original mint luster and sharp striking details. The error occurred during the minting process, making each such coin a unique documentation of an RBI production anomaly—these mistakes are intentionally withdrawn from circulation once discovered, making surviving examples increasingly scarce.
For numismatic enthusiasts and error coin collectors, this represents a significant acquisition. Rotational errors command premium valuations in the collector's market due to their rarity, historical documentation value, and the narrative they tell about minting operations. This Calcutta Mint piece embodies both monetary heritage and mechanical fascination, serving as both an investment-grade collectible and a tangible piece of modern Indian numismatic history.
