No, the way I see it, if nasty deflation comes that nickel might buy that loaf of bread; if a nasty inflation comes you can sell that nickel for near intrinsic value (like silver coins today) and buy that loaf of bread with the proceeds.
While a tad bulky, $1,000 in nickels at 10x face returns $5,000. Not a bad return in exchange for tying up some bucks for a year or so.
$10,000 (brain flatulence).
