Preserving Wheats?

my wheats are dry looking is there a way to preserve them to make them look a little less dry?
thanks.

I rub mine with a little bit of vaseline. Makes 'em looks nice.

thanks swartzie.
i have hundreds stored away in a ziplock bag.
is there something i could mix with the pennies to keep themfromdrying out.
thanx all!

Your first step is to remove all the the adhered dirt and gunk on your old cents, using water and a soft toothbrush. When all the dirt is gone from all the nooks and crannies on both sides of the coin, swab it with a light coating of olive oil which mimics the natural oils of the the body and you will see a coin with greater detail and  reflection.

  Maybe look at Blue Ribbon coin conditioner.
