If it really is hyperinflation, then you should buy stuff that you will need in the future like canned goods and food that will store for a long time. These items may not even be available at any price.
Loose silver coins of the 1964 and earlier dates are the best to have. They come in a variety of denominations and it is easy to break up a $500 face value bag. Dimes, quarters and half-dollars are easily recognizable by people and you can easily compute the value by just using a factor over face value.
Gold is easy to store as it is less heavy per value and you can easily store it in a safety deposit box.
Stay away from US paper assets.
However, you should be hedged which means that you should be prepared for inflation, stagflation, hyperinflation and deflation. Good luck.
