A copper-alloy disc featuring the number XIIII on the reverse and an image of a couple in a sexual embrace on the obverse, found on the banks of the River Thames in Putney. It remains undecided as to whether this is an actual token, used to pay for the services of a Roman prostitute, or just a raunchy gaming counter. Either way, it is an incredibly rare find from Britain's Roman past. The finder, Regis Curson, has generously donated the item to the Museum of London.
