Here's a story.
Back in 1964 gas was around 25 cents per gallon, and a quarter contained 90% silver. And then the silver coins were replaced by non-silver variants.
Anywho if you head over to coinflation you can see that one of those 90% silver coins has a melt value of $3.23; gasoline here in PA (with the second highest state tax in 'Murica last I checked is around $2.46
Now, has gas gotten more expensive, or has the dollar lost value? Perspective.
If the dollar falls in value the .gov will have to replace the nickel with something of lesser melt value, because it will no longer be economical to produce nickels ... so it might behoove one to start stockpiling nickels....

IF the dollar falls in value, and it certainly should with all the printing going on THEN the nickel will be abolished and replaced with a lesser metal, or even plastic; who knows?
A few thousand dollars of nickels may be the most safe trade you personally can make, frankly. No matter what, they won't go down in face value aaaaand they may actually increase in value the way the pre-1964 US 90% silver coins have.
Say, would you like to buy $100 face value (ie 400 quarters) of those 90% silver US coins? That can be done [here]https://www.moneymetals.com/pre-1965-junk-silver-coins-dimes-or-quarters/35) among other places and will set you back around $1500 ...
