The Rooswijk was a Dutch East Indiaman bound from Amsterdam and the Texel to Jakarta, which floundered after grounding on the Goodwin Sands at the end of 1739. The site, discovered in 2005, now a designated site under the Protection of Wrecks Act 1973, had already yielded some 1,000 artefacts including some 553 silver ingots, including the present example. The ingots, each approximately 4 lbs in weight, were made from silver mined in Mexico and sold to the Amsterdam Chamber of the V.O.C. They were destined for use in the coinage of Batavia. Other examples from the cargo were sold Christie's, London 24 May 2018, lot 488, 14 November 2018, lot 519 and 30 January 2019, lot 21.
