Is this an error coin? It's stamped 1994 D an has silver on the side it found it in a box of halfs today can someone help me out pls
To venture a guess, I'd say this coin is probably not silver. When planchets (sp?) are made, they are punched out of ribbons of metal that are rolled with the various layers of the desired coin pressed together under pressure. Sometimes, the ends of those ribbons will contain all of one kind of metal. It looks as though you got a coin that was punched out of a ribbon with very little core material present, thus, the sides of the coin show no core material and appear uniform with the obverse and reverse clad material. That's my guess. You could confirm this with a very simple and inexpensive silver acid test.
Thanks @ green18 I try to do my best at this coin collection I'm bearly starting it's Bearly my third box
One way it to weight it. The weight should be for clad: 11.34 grams; silver clad 11.50 grams; silver 12.5 grams. Then it could be, a silver planchet for a sliver poof, that was hung a bin and shipped out with clad planchet. shipped to Denver and minted.
They're easy to find online. They basically work by putting a drop on whatever you are testing and seeing if it changes color. The local coin shop might have one or even do one for you. edit: I forgot, an easy way is to do the ping test. Hold the coin balanced on the tip of your finger and tap the edge with another coin. Clad will sound flat, while a coin struck out of silver will ring much higher and resonate. If it sounds the same as a clad, it's clad. If it "pings," it's silver.
