If interpreted as it’s probably intended, this is basically about maximizing the amount of information lost in the memory-wipe stage. A good strategy might be to choose some large volume that can’t easily be scanned—your lawn if you have a house, the cracks between the floorboards, et cetera—and use some indexing system to pick random coordinates. Better yet, pick several such volumes and pick randomly between them. Add some random debris to throw off metal detection. Move furniture around to create red herrings. Hire a friend to rearrange your stuff for a day and let them do the hiding. If you live in an environment conducive to it and the reward’s big enough, move to a different but internally identical space—another apartment in the same building, say—and match the old space’s internal configuration as best you’re able, with the target left in the old one. There are a lot of options, but most of the reasonably good ones already constitute a near-guarantee of success.
A more creative strategy might be to set up consequences for retrieval which exceed the reward you’d be getting: for example, to hide the coin in your compost pile and then mine it with explosives, with the mined region clearly marked and a deactivation timer set to go off after the deadline has expired. The threat can always be made credible because you have essentially perfect information about the personality making it.
