While a Treasury order of 1886 made provision for the preservation of suitable objects in various national museums and payment of rewards to their finders, the Crown is under no legal obligation to offer any rewards for treasure trove objects it has claimed. However, it usually does so, using the objects' market price as a guide. A reward may be withheld or reduced if the finder has inappropriately handled an object, for instance, damaged it by cleaning it or applying waxes and varnishes to it. Finders may elect to waive their rewards. Rewards are not paid for finds occurring during organized fieldwork.
