Quote: Nice pair! How did they determine it's a 1982 planchet?
Separated, you are correct... it is an unstruck coin of nickel composition, from any given year. But they were submitted together to PCGS with a long explanation.
They both came from separate paper-wrapped Constitution dollar rolls. That does not necessarily prove anything, but with nickel dollars, the blanking strip is only wide enough to punch four blanks at a time. That means there could be four (or less) possible triple clipped blanks with the clips in the same spot, which one would assume would be all struck - the odds of finding a triple-clipped blank with the exact match of the struck coin was enough for PCGS to come to the same conclusion as me...
Individually, they are not worth much to an error collector - together, this is one of my favourite errors in my entire collection...

We talk about 'planchet' clips, but almost all of the genuine examples are blank clips. It seems very improbable to my mind, that a planchet would be clipped after the blanking process.
Be careful, and always check that the coin itself has not been clipped post mint, (and thus is a fake), so called 'planchet clip'. Strictly speaking, genuine clip errors should be more accurately called 'blank clips'. The Blakesley Effect can almost always be seen on coins have have been clipped during the blanking process, and thus is a good diagnostic for an error clip coin, to help distinguish a fake clip from a genuine clip error.
Very minor clips do not add much extra value, but nevertheless are always very collectible. Unfortunately with very minor clip coins, the Blakesley Effect is not always apparent, even for genuine clip errors.
