Error question

Received a 1982 P Roosevelt dime in change. Instead of 3 layers, copper surrounded by silver, the coin has 2 layers. The obverse is silver and the reverse is copper. Both sides are struck very sharp and clear. Is this common?

been struck after splitting. Look at the edge; it should either be all dark copper
color or it should be mosly "silver" color toward the obverse side. If neither than
it's probably plated on one side. The weight will be the best indication. A regular
coin will weight about 2.3 g.
A missing clad layer is by no means common.
Yes this makes sense. The State Quarter series has created a new set of collectors (it's what got me started). Since the State Quarter series began, a major error such as your missing clad layer or major off-center strikes (where a significant portion of the coin face is missing) or coins with multiple strikes (i.e. the coin gets stuck in the machine and the coin gets turned a little with each re-stike of the machine resulting in multiple images on the coin) have been selling easily from $100 to $500.
But not as many people are collecting modern cents, nickles, and dimes. There isn't anything "new" about these coins, so a major error on them doesn't pull as much of a premium.
<< <i>If it's missing a clad layer, it should be thinner than normal, and lighter in weight. If the thickness and weight are normal, then it's probably plated. >>
Not always. When the strip is rolled, at the ends it is possible for there to be just two of the layers present but the thickness is still correct. (As it is rolled it smears out. Think of the ingot as a rectangle of three metal layers. As it gets rolled it is squashed over into a parallelegram asnd drawn out so from end to end you get just bottom layer, bottom and middle, all three, middle and top layer, just top layer.) Normally those ends are trimmed off before the blanking is done but if the strip isn't trimmed properly it is possible for part of the two layer section to remain. Planchets cut from this section will be proper weight, since the thickness is correct, but with only two layers.
