I am not sure the price will be that high soon. Like I said, I bought a Prithvi coin ( I have two such coins of Prithvi Narayan) for about thirty dollars not so long ago. I wouldn't recommend Sajha users to pay that high. I just think it would be surprising if some foreigner buys the coin for that much. I was about to buy a book, published in Janga Bahadur's time, long ago in ebay. The price of that book shocked me, it sold for more than 400 dollars. That book was the highest priced book on Nepal I have ever known. The book was called something like History of Nepal, and was a translation of vanshawali.
