LOL! Yes, you're completely right. My point was that the '43 steel penny had been copper-plated, which means it's a counterfeit, so it can't be sold; it's worth nothing in the context of numismatics.Wrong. Go to the hardware store and price a quarter inch washer. Now you know what a zinc lincoln is worth. They make great washers. Size the hole to suit. If you need a stainless one, use a nickel.
As you say, though, it could have some value in another form down the road.
