The coins are scarce and highly in demand. The prices should vary about 40-50k for the Silver 5 Kori, and about 60-80k for the Gold. Silver 1 Kori of the type is not very scarce and should be about 1200 - 1500 Rupees. But again, these prices would depend on the condition of the coins, and anything which is in lower condition or damaged in any way like edge nicks, test marks etc. would be very low in price.
