Are you referring to doubled dies (Varieties) or errors? Many DDR's and a few DDO's this LP2 series. I don't think any of the Denver ones has been found yet. There are die clashes on the obverse known and I found two Feeder Finger Damage to a die coins. (You will hear more of that in a few months.)
But errors would include Off Center, wrong planchets, clips (incomplete planchets) doubled struck, unplated planchets and on and on. But die cracks, die abraiding, die deteriation, die wear and others can happen in any year/mint mark/series/denomination/country. These are not errors or vatieties. They are just run of the mill as the die ages.
