1200 Réis - Luis I Countermark 'BIG CROWN' over 1 Thaler - Maria Theresa, Austria

Historical Context: The 1881 1200 Réis countermark on a Maria Theresa Thaler from the Azores represents a critical monetary solution under Portugal's King Luis I. Facing severe currency shortages, Azorean authorities officially revalued foreign silver. The "BIG CROWN" countermark transformed the widely accepted Maria Theresa Thaler into 1200 Réis legal tender. This pragmatic intervention stabilized the islands' economy, demonstrating resourceful monetary policy in a colonial setting.

Artistry: The host Maria Theresa Thaler, an 18th-century Austrian coin, features Empress Maria Theresa's elegant draped bust, characteristic of late Baroque numismatic art. The "BIG CROWN" countermark, conversely, is a utilitarian design. Struck prominently on the obverse, this bold, stylized Portuguese royal crown marks official revalidation. Its artistry prioritizes authoritative simplicity, conveying royal endorsement, often obscuring the original design.

Technical/Grading: This coin's technical aspects involve two distinct strikes. The original Maria Theresa Thaler’s high points include the empress’s hair and diadem. The "BIG CROWN" countermark’s strike quality varies significantly, from sharp, deeply impressed examples to weak or off-center applications. High points for the countermark are the crown's jewels and band. Underlying wear on the Thaler is common. Its 28g weight and 41mm diameter in .833 silver are inherited from the host coin.
