2014-11-04KavindaIdentify ancient coins101010NoReply: Ah such as the imitated roman coins of ancient Lanka as i read on your website, it's interesting. Well sir actually, i'm not a collector and i don't have a collection, these are the only ones that i have which my mother gave me. Unfortunately the rest of my grandfathers collection was said to be sold back in the 80's. i was just interested in finding out the numismatic value of these coins. I really appreciate your offer to support :) Thank you very much once again.. and please continue your good efforts :) Kavinda.

2014-07-05Percy S10 RUPEES of Ceylon101010YesDear Sir, Many thanks for your prompt reply and helping me understand the sub-prefixes of this beautiful series of KG VI 10 Rupees from 1941 to 1948. Sir, it has taken me 12 years to come close to completion of these J1 to J47 series notes (including date breaks) and I am now missing only J46 & J47 sub-prefixes in my collection. Hope someone can help me in this. Your site is excellent with so much details, something which I had never known before. Hope to follow your site lakdiva more closely to gain knowledge and thus help me in my 10 RUPEES collection of Ceylon. Thanking you Sincerely once again. Warm Regards from India, Percy Siganporia
