John1 Moderator United States 56855 Posts	Posted 05/25/2018 11:37 am Looks like a minor MAD,misaligned die obverse. If it was off center strike it would be off the same on the obverse and reverse.Not off enough for a premium. John1 Edited by John1 05/25/2018 11:37 am Report this Post to the Staff
Crazyb0 Rest in Peace 10197 Posts	Posted 05/25/2018 12:17 pm When dies become loose in their holder this MAD happens at the strike, they tilt slightly. It usually happens on the hammer die but can happen on the anvil die. It becomes interesting when the reverse is affected and not the obverse or both side show a MAD in different directions. An Off-Center strike generally refers to a coin struck in the chamber but not having the collar deployed(up) to make the rim. These are also called Broad strikes/out of collar strikes and actually make the coin larger, out of round. Off center refers to to at least part of the details being missing(edge letters).

I believe that the Mint official tolerance allows misaligned or off center strikes up to the point that parts of the die are cut off, so this really can't even be called an error because it would pass QC at the Mint.

coop Bedrock of the Community United States 62064 Posts	Posted 05/26/2018 01:12 am Actually a MAD event can only happen on the hammer dies. Why? Because the anvil die is not able to be adjusted . It is in a fixed position. The hammer dies are adjustable. If not centered over the planchet, then you have a MAD coin. If the adjustment is way out of alignment, then we find collectible MAD coins that the devices fall over the edge of the coin. If these are not corrected, then the die suffers die attrition. But, on the newer cents you cab find this on the reverses as the dies setup changed. What does that mean? The hammer die for some coins are the reverse die. Instead of the hammer dies in the past were only on the obverse. 1995 was when cents changed over So now we have to look at reverses for these.
