Baldwin's will offer the final part of the landmark David Fore Collection of British Indian Coins on September 25-26 in London, with an Indian Karauli gold mohur set to see some of the highest bids.
The Indian Karauli gold mohur.
The auction will be held during Coinex Week, with Baldwin's acting as the Official Coinex Auctioner for 2013.
This third part of the collection focuses on circulating coins of British India, East India Company presidencies and the Indian native states.
The gold mohur, a stunning example from the princely state of Karauli, is expected to sell for £7,000-9,000 ($10,967-14,101). In extremely fine condition, the rare 1888 piece is a choice specimen, yet is marred by light marks in the central reverse surface.
Further highlights include a gold mohur issued under the reign of Kitendra Narayan, the maharaja of Cooch-Behar, in 1914. In mint state and with a particularly fine strike showing plenty of detail, it is valued at £5,000-8,000 ($7,834-12,534).
An AH 1176, Year 4 Monghyr coin, with a £4,000-6,000 ($6,249-9,376) estimate, will also feature.
Part two of the David Fore Collection was highlighted by the record sale of an 1839 silver pattern rupee, which made $204,000, a new world record for any British Indian silver coin. The first instalment saw a proof restrike of the 1878 mohur sell with a 212.2% increase on estimate.
The auction also stars The Arielle Collection of British Colonial Coins, which provides the highest valued lot in the form of a gold 5 riyals coin from Zanzibar, issued in 1882 under the rule of Sultan Barghash ibn Sa'id.
Another coin prized for its scarcity, this example is in good/extremely fine condition, warranting an estimated value of £8,000-10,000 ($12,534-15,668).
Paul Fraser Collectibles has a superb selection of rare coins for sale, including an 1831 William IV proof crown, which shows both varieties of the coin through a single altered obverse die - a rarity that has never been recorded before.
