Of course the mudlarks lacked coins to begin with. They wanted capital. John Cole – the biggest and boldest of the fellows who'd stolen the longboat – hit upon another shrewd plan: they would steal the only parts of ships that could be reached without actually getting aboard first: namely, anchors. They'd then sell them to the captains of ships who had found their anchors missing. This scheme had the added attraction that it might lead to ships' drifting down the current and running aground on oh, say, the Isle of Dogs, at which point their contents would be legally up for grabs.
