I would get more use out of a stick of chewing gum (does it still come in sticks?) than a 1973 dime unless the plating was about half an inch.
If you want an oddity, then do like I did when I found the Obama 2008 half that was gold-plated and had some "painting" on it. clean it of the dirt (painting) and just look at a weird gold looking coin that is prettier than the SAC/NA/Pre$ coins. They tend to turn an ugly brown like one of those hollow easter rabbits found in the floor of your car, melted, at new years.
