Hooks and bullets. Fishing tackle and nets. You cant eat gold, but you can eat fish and shrimp, and know what plants you can eat. I remember there was an archealogical dig on a European castle that was under siege by Napoleon, I think, and the corpses found buried in the moats, still had the gold in their pockets, and they had written that during the brutal winter, under siege, that bread was worth 10 times it weight in gold. Might be a good idea to get a few big bags of rice, sugar, flour, lard, oil, salt, vinegar, baking soda. None of these items will go bad and can become valueable commodities during bad times.
