I don't really know what I'd do with it. The one thing I know that I would definitely NOT do is put it in a bank safety deposit box. No-Freaking-way, gold is just too easy to liquidate as commodity.
Speaking of liquid, I heard of a guy that keeps a bit of gold as a chloride. Auric chloride is a liquid. If you don't know how to separate the two elements it would be essentially worthless. Even if you know he had it you might not figure out that it ain't sloe gin.
