Certified 1808 Madras Presidency 10 Cash copper coin from British India, professionally authenticated by Numismatic Guaranty Company under its shipwreck certification program and identified as recovered from the historic wreck of the Admiral Gardner. This curated example belongs to one of the most collected East India Company maritime coin issues, struck for circulation in southern India under the Madras Presidency during the early nineteenth century when copper cash coinage formed the essential low-denomination monetary base of British colonial trade across Madras, Calcutta and Bombay commercial routes. The obverse displays the East India Company arms with shield, banner, and heraldic supporters, a classic design associated with the expanding commercial authority of the British East India Company across the Indian Ocean. The surrounding inscription clearly reads United East India Company, with the 1808 date placed below, connecting the piece directly to the Napoleonic-era maritime trade network linking London, Madras and Southeast Asian ports. The reverse carries the denomination expressed in Persian and regional script, together with the Latin denomination line X Cash, representing the multilingual monetary policy used for circulation in colonial India where local commerce required recognisable bilingual or trilingual denominations. The historical significance is strengthened by its documented shipwreck provenance. The Admiral Gardner, an East India Company transport vessel, sank in 1809 off the English coast while carrying large quantities of newly struck Madras Presidency copper coinage destined for India. Coins recovered from this wreck are highly sought after because they preserve both colonial monetary history and maritime archaeological provenance. Shipwreck-certified examples from this cargo are especially attractive to collectors because they combine East India Company numismatics, British naval history and documented seabed recovery context within a single certified holder. The coin retains original copper surfaces with visible marine toning and subtle shipwreck-related patination, typical for authenticated Admiral Gardner recoveries. At 4.7 grams, this piece corresponds to the standard reduced-weight copper cash issues struck during the period when the Madras Presidency adjusted coin production for practical circulation demands. The certified holder and verification number provide strong market confidence for collectors of British India, colonial trade coinage, East India Company emissions, maritime archaeology and early nineteenth-century Asian circulation types. This is a highly recognisable certified colonial issue with clear historical linkage to Madras, British India, East India Company shipping and one of the most famous documented numismatic shipwreck recoveries in the world.
