1 Dinar - Vladislav I jointly with Radu I Type Ia

Vladislav I and Radu I issued coinage jointly during a period when Wallachian succession operated less as a clean transfer and more as a negotiated co-rule — Radu serving as a designated heir with recognized minting authority before his brother's death. This type reflects that arrangement directly. The MBR Type Ia classification places it among the earliest die groupings in the joint series, distinguished from later types by subtle differences in die execution that specialists use to sequence the emission.
