Two new discoveries have puzzled me greatly. One is that there is also a “Sa” imprinted on the Tibetan silver Sichuan.
The other discovery is the term “Nyingtam Ghatikap”. The terms translate to: Old Coin from Ghatika. This means that our silver coins were hammered in a mint located in a place called Ghatika. As you know if a person from Chapcha is named Tshering, he would be called Chapchap Tshering; Dagap Thinley; Sharchop Pema etc. Likewise a coin hammered in Ghatika would be Nyingtam Ghatikap.
There is a place called Ghatika in West Bengal, India. But I am now trying to find out if there was a mint there during the ancient times.
According to History of Bhutan by Bikram J. Hasrat, the term he uses is Ngultrum Ghatikha. But a knowledgeable person in Bhutan says that the term should be: Nyingtam Ghatikap. The term Ngueltrum came much later. The person says that his late father would pronounce the terms as Nyingtam Ghatikap.
