Admiral Gardner

The final voyage

Admiral Gardner was an 813-ton East Indiaman, launched on the Thames on 12 April 1797 for the British East India Company. She made five earlier voyages to India and China; on her sixth, she left London on 25 January 1809 bound for Madras, carrying roughly 46 tons of newly struck Madras Presidency 'X cash' and 'XX cash' copper coin, minted by Matthew Boulton's Soho Mint in Birmingham and packed in wax for the voyage.

Barely clear of the Thames Estuary, the ship became becalmed in the Downs anchorage, then was caught by a violent gale. She broke from her moorings and was driven onto the Goodwin Sands — the notorious shifting shoal known to English sailors as 'the ship swallower.' Nearly all aboard survived thanks to local Deal boatmen, but the ship and her entire cargo were lost.

What was aboard

The ship's copper cash cargo and its value are documented in East India Company and salvage records; this list covers the recorded cargo type, not a coin-by-coin tally.

Madras Presidency 10 cash coins: Copper coins struck at Boulton's Soho Mint for circulation across the Madras Presidency.

Madras Presidency 20 cash coins: The larger companion denomination shipped alongside the 10 cash coinage.

Ship's ironwork and fittings: Cannon, anchors, iron bars, and copper ingots recovered from the wreck site alongside the coin cargo.

How to collect

Check for NGC shipwreck certification: Many genuine Admiral Gardner coins carry NGC 'Genuine — Admiral Gardner Shipwreck' certification, a useful (though not sole) verification point.

Denomination should match the cargo: Authentic material is Madras Presidency 10 cash or 20 cash copper — other denominations claimed as 'Admiral Gardner' warrant scrutiny.

Expect encrustation and fused clusters: Many coins were recovered still bonded in corrosion masses; individually cleaned pieces should show consistent surface characteristics.

Understand the recovery era: Nearly all market material dates to the 1984–1985 salvage; claims of 'recent' recovery from this now heavily salvaged site deserve caution.
