I saw this one in ebay. I am not sure it is worth that much, though. I also own it, and I paid something below thirty dollars when I bought it. There might be other coins in KTM, where people will be willing to sell for less. http://cgi.ebay.com/Nepal-Prithvi-Narayan-Mohar-Extremely-Rare-Type-1763_W0QQitemZ320073630866QQihZ011QQcategoryZ534QQrdZ1QQcmdZViewItem#ebayphotohosting
