Dinar - Jayanaga Prakandayasas Karnasuvarna

Karnasuvarna served as the capital of the Gauda Kingdom in what is now West Bengal, reaching its political peak under Shashanka — the ruler who briefly unified much of northern and eastern India in the early seventh century and is notable as one of the first Hindu kings to actively suppress Buddhism in his territories. The Jayanaga issues postdate Shashanka's death around 625 AD, appearing during the fragmented succession that followed, when regional rulers scrambled to assert legitimacy through gold coinage closely imitating late Gupta types.

The Mitchiner LOW references place this firmly in a transitional monetary moment — Gupta imperial authority had collapsed, but the prestige of Gupta gold remained the benchmark against which any eastern Indian dynasty measured itself.
