Antiques or jewelry items that have been stolen and hidden away. Chiefly of British usage, a sleeper is an item of antiquity, generally of known provenance, stolen and cached, sometimes for years, until it can be sold to a private buyer or exchanged.
"A sleeper is an item that has been deliberately hidden, usually because it is hot." Lovejoy, "To Sleep No More," 1987.
